The description of Orthurethrous snails is continued in this volume, the remaining groups of Ferussacidcs and the Partu- lidcs being described. In treating of the latter family, the author has had the advantage of studying the types and other specimens of the late Dr. W. D. Hartman, now forming part of the collection of the Carnegie Museum at Pittsburgh. The conclusions reached in the monograph now published have thus been based upon the material of two large collections. The liberality and courtesy of the Trustees of the Museum and of the Director, Dr. William J. Holland, are here grate- fully acknowledged.

. INTRODUCTION.
About ten years ago the writer pointed out the existence of three great groups in the monotremate land snails, based upon the structure of the pallial organs: SIGMURETHRA, HETERURETHRA and ORTHURETHRA. The first group includes a very large majority of the land snails now existing, which have been described in volumes I to XVIII of this work. The Heterurethra are chiefly represented by the genus Suc- cinea. Finally the group Orthurethra is made up of a series of families which retain primitive pallial structures like the Basommatophora. They are the scattered descendants of snails of long ago — of the first land-snail fauna. With the rise of the Sigmurethra, these primitive snails declined. On the continents they take a minor role, and seem to exist by grace of their insignificance (Pupillidce, Valloniidce, Ferus- sacidce), though one family, the Enidce, contains snails of moderate size. On the Pacific islands, where the Sigmurethra are represented by only a few low forms, Orthurethra are still dominant. In this island world the Partulidce, Amastrida, Achatinellidce and Tornatellinidtf comprise the most con- spicuous elements of the snail-fauna.
The following families are now comprised in the group Orthurethra :
Valloniidaj (See Vol. VIII, p. 247, and IX, p. 282). Holarctic.
Enidae (Buliminidcz of authors). Palaearctic, Oriental, African.
Pupillidae (Pupida of authors). World-wide.
Partulidse (this volume, p. 155). Polynesia, Melanesia, Micronesia.

calloused. Animal blind, or at least without pigmented eyes. Jaw composed of many narrow plaits. Radula with 11, 1, 11 teeth in C. acicula, 18, 1, 18 in C. gundlachi, the central tooth much smaller than the laterals, with a tricuspid reflection. Laterals symmetrical, tricuspid. Marginal teeth low, wide, with two low, denticulate cusps. The genitalia, as figured by Lehmann for C. acicula (pi. 15, fig. 1) have the duct of the spermatheca very short. An appendix, enlarged at the end, is terminal on the penis. There is also a short accessory organ anteriorly on the penis.
Type C. acicula Miill. Distribution, Europe and most tropi- cal and subtropical countries.
An excellent account of Csecilioides acicula has been given by Mr. L. E. Adams, as follows: " Methods of Progression. — Usually the shell is dragged along the ground after the animal, though more rarely it is lifted to a horizontal position (pi. 1, fig. 6). On two occasions I observed the animal protrude its head under the shell towards the spire and progress in that direction, forc- ing the shell along the ground in front of it, apex first, and then lift the shell over its head at an angle of about 45 degrees, and continue its march in that position (fig. 5). The progressk n is always by slow jerks, and not a continuous glide. I have not observed the shell carried in the position of Jeffrey's figure (British Conchology, Vol. I, pi. 7, fig. 18), though Nilsson says ' the animal sometimes carries its shell erect, but generally drags it along depressed.'
" Texture and Form of the Animal. — I was much struck with the extremely flexible and elastic nature of the animal. I have observed one emerge from the shell as it lay flat, on a hori- zontal surface, and make a complete circle with its head and tail, without moving the shell. It is also remarkable how far the animal will protrude from the shell, and how slender an attachment connects the head and foot with the part within the shell. The end of the tail is often curled up. Along the neck and down the front of the head are two mucus sulcations on cither side of the dorsal line (pi. 1, fig. 8). The tail is pointed and sharply carinated; from the dorsal ridge mucus sulcations descend to the lower edge (fig. 7).
C^CILIOIDES. 3
" Eyes and Tentacles. — Jeffreys' enlarged figure (Brit. Conch., Vol. I, pi. 7, fig. 19) is not quite accurate. He seems to have taken his description from Nilsson, and it may be doubted whether Jeffreys himself examined the animal with sufficient care. Nilsson had evidently studied the animal, but he was not correct in describing the upper tentacles as ' not thickened.' In all the specimens that I have observed the upper tentacles are certainly slightly bulbous when fully or nearly fully ex- tended, though this does not appear when they are only slightly protruded. Nilsson, however, correctly remarks that the apices of the upper tentacles are not 'marked with a black spot.' Now Lamarck (to whom Nilsson refers) seems to have been the only one to observe the colorless eyeball, and he did not recog- nize them as such. Nilsson says (quoting Lamarck) "In this species no eyes indeed are exposed, unless they are white, like the tentacles themselves. These, indeed, are terminated by a convex surface, very smooth, very shiny, surrounded by a slightly impressed ring; which surface doubtless answers to the eye of other terrestrial mollusks. But this animal, probably because it lives underground, where it cannot use eyes, appears to us plainly to lack eyes.' Now I have noticed that these peculiar convex endings with a constricting ring are in fact eye- balls, and also that they are retractile, but whether they have retained the power of sight in spite of their loss of pigment, I am not prepared to say (see fig. 8>. As far as my observation goes, the animal is insensible to light, though it will crawl straight away to a heap of moss; the direction, however, may be determined by scent alone. If it is deficient in sight it cer- tainly uses its tentacles to all appearance in the same manner as its more favored brethren. I may mention in this connection that an albino specimen of Limax maximus, whose eyeballs were also destitute of pigment, seems to act in a perfectly normal manner. Though my observations on this point (Journal of Conch. , Vol. 9, p. 24) tend to show that this species is lacking in sight, I am not aware to what degree of perfection the vision of terrestrial mollusks attains, but I have noticed that Cydostoma elegans and Helix pomatia seem sensitive to the approach of a large object." (Lionel E. Adams in The Journal of Conchol- Vol. 9, p. 207.)
4 (LECILIOIDES.
Caecilioides is well known to inhabit graves. Gaudry found them in lacrymatories unearthed from Grecian tumuli. Rev. H. Housman records that near Chichester in "an early British burying-ground many skeletons were found. The bones, which lay about three feet below the surface were infested with A. odeida" (Journ. of Conch, iii, 1882, p. 317). In North- amptonshire Messrs. Wright and Adams found C<zcilioi,des abundant to a depth of 4^ ft. , in a place where skeletons of men and horses have occasionally been discovered (J. of C. viii, 1897, p. 395). J. W. Horsley reports them similarly from a Saxon cemetery near Witney (J. of C. ix, 164); and in Germany Professor von Martens has recorded the presence of a great num- ber of large fresh specimens in a human skull dug up at Bern- burg (Nachrbl. d. Mai. Ges. 1883, p. 60).
Definite information upon the food of Caecilioides is wanting, but they probably feed upon vegetable matter, such as subter- ranean fungi or possibly fine rootlets.
The European species of Ceedlioides have no doubt been multi- plied beyond reason, yet without a critical study of the types it is impossible to say how many recognizable races exist. M. Bourguignat and his friends had an agreeable custom of describ- ing "species" from single selected specimens, ignoring connect- ing forms. Published figures of shells they had never seen occasionally served as a basis for supposed new species; so that in the identification of real shells there is some excuse for pass- ing over much work of these authors with a light heart and careless eye. I have neither the time nor type-material to at- tempt a critical revision of these forms. It is a work which properly belongs to some European student who will make a study of the local races, of the significance of variations, whether individual or racial, and finally he must study Bourguignat's types. This work demands great application and large series of the shells, unprejudiced by selection or determination. I have been able to do little more than give an account as full as the original sources admit. The American forms are treated more fully, my material being ample, and the literature less overloaded.
The generic name has been variously spelled, but the earliest

valid form is undoubtedly Csecilioides, in reference to the blind- ness of these tiny subterranean snails. Aciculina of Wester- lund is an absolute synonym of Cxcifioides, having for type the same species, C. acicula.
Csecilioides occurs in typical species in the Miocene and Plio- cene, the following species being known. All were described under the name Csecilianella.

According to Wollaston, this species differs from C. acicula by being smaller, narrower, thinner, paler, more highly polished and more transparent; its spire, which has a volution less, is shorter and a little more obtuse at the apex, its suture is less oblique, its columella is relatively somewhat longer and etraighter, and more flexuous, and its entire outline is both narrower and more fusiform.

2. C. EULIMA (Lowe).
Shell linear, very narrowly cylindric, very slender, generally very indistinctly curved; spire long subconic-cylindric, the apex obtuse; suture very oblique, distinctly margined. Whorls 6£, flat, the middle ones long. Aperture ehort-obovate, acuminate above, entire and arcuately rounded below, much shorter than the spire; parietal wall uniplicate in the middle, the fold trans- verse, entering; peristome simple, acute, the margins joined by a somewhat thick callus, the right margin rounded, continued in a regular curve into the basal and columellar margins. Col- umella curved and slightly twisted, not abruptly truncate, but gradually and easily passing into the basal margin. Length 2.5 to 3, diam. 0.75 lines (Woll.).
Madeira: probably in the Funchal district, recent; Porto Santo, very rare, fossil (Wollaston').
Achatina eulima LOWE, P. Z. S. 1854, p. 201. — WOLLASTON, Testacea Atlantica 1878, p. 244.
"The most important feature which separates the A. eulima from the acicula consists in the presence of a conspicuous medial plait on its ventral paries ; but it has other characteristics also which combine to separate it from that species. Thus it is not only longer, more cylindric, and proportionately still slenderer, with a tendency to be obsoletely bent (as in the marine genus Eulima'), but its whorls (particularly the intermediate ones) are altogether more lengthened-out and flattened, and its aper- ture is relatively a little shorter, as well as broader (and more rounded) posteriorly, the basal margin being more obtusely arcuate, and merging almost without an intervening angle into the columella, which is narrower gradually (and is not abruptly truncate) behind. The suture is exceedingly oblique, and its surface is of a hyaline white." (Wollaston).
This species apparently belongs to the section Rhaphidiella of Maltzan. See species No. 6.

those above on account of the more rapid descent of the last two turns of the suture. The suture is distinctly marginate. The outer lip is strongly convex in profile view, the greatest con- vexity being below the middle. Columella strongly concave, not heavily calloused, narrowly, subvertically truncate at base. Parietal callus hardly perceptible. Length 4.1, diam. 1.3 mm.
Madeira: Under stones in dry places (Albers); Punta Sao Lourenco. (M. Grabham).

This species is distinguished from C. acicula by the irregular increase of its whorls, the antepenultimate or penultimate sud- denly widening more rapidly than those before, and by the narrow, subvertical truncation of the columella, that of acicula being wider and more approaching horizontal. The species of Bourguignat was based solely upon Albers' account; and the latter, in my opinion, applies to this form rather than to the real C. acicula. Bourguignat had not actually seen the Madeiran shell.
The Sicilian C. actoniana, rizzeana and petitiana are apparently identical specifically with nyctelia, — or at all events, there seems to be no difference in the shells. How many other of the "species " are really the same I do not know. Fig. 32 repre- sents an adult shell from Punta Sao Lourengo; fig. 33 a young shell from another locality, length 3.6, diam. 1.1 mm.
Var. maderensis n. v. PI. 2, figs. 34, 35. The shell is com- posed of 5 nearly flat whorls, the last turn of the suture de- scending more rapidly.

"Shell turreted and slender, transparent, very thin, highly polished and iridescent, ivory-white, with a yellowish tinge on the upper part in fresh specimens (owing to the color of the liver), perfectly smooth and polished when examined with a lens of ordinary power, except a few faint and irregular wrinkles in the lines of growth, but under a microscope exhibiting deli- cate and close-set spiral stride. Periphery rounded. Epidermis exceedingly thin and forming a mere film. Whorls 5^, not convex, but compressed and drawn out, rapidly increasing in size; the last occupying about one-half of the shell. Spire very obtuse and rounded at the point. Suture moderately deep and oblique, apparently margined on the under side by reason of the upper part of the succeeding whorl being seen through the pellucid shell; mouth oblong, contracted by the penultimate whorl, narrowing above into an acute angle, slightly widened and rounded below, but interrupted by a deep notch at the base of the pillar lip." Outer lip thin and flexuous. Pillar lip thick and curved. Inner lip consisting of a slight deposit of shelly matter, which is spread on the pillar. Length 0.175, breadth 0.04 inch (Jeffreys').

Gwyn Jeffreys' description of this common species is given. It seems to be a rather variable form, but the limits of variation in this group are little understood. A large proportion of the specimens in collections are from drift debris of rivers, hence forms from various colonies and diverse stations are mingled in unwonted company. Such lots are misleading in the study of variation.
Var. elongata Locard. Of a slimmer, more lengthened form.
Var. ventricosa Locard. Of the same size (not over 4.5 mm. long), but the shape is a little more ventricose, more swollen at the base (Locard, Conchyliologie Portugaise, in Archives du Mus. d'Hist. Nat. de Lyon, vii, 1899, p. 141).

Var. anglica Bgt. According to Bourguignat, this is dis- tinguished from acicula by the larger size, — length 8, diam. 1.5 mm. — the whorls of the spire more convex, the suture deeper, not margined, the aperture rounded, and the columella strongly truncate. England. (C. anglica BGT., Rev. et Mag. de Zool. 1856, p. 384, pi. 12, f. 4, 5.)
This "species" is a good example of Bourguignat at his worst. There really was no type specimen of anglica; nothing but Reeve's figure in the Conchologia Iconicav, pi. 20, f. Ill, which Bourguignat described in formal phrase, while his artist redrew it enlarged for his plate. The citation of Reeve is curi- ously falsified in name of the work, number of the figure and date, almost concealing the real source of all of the information extant upon " C. anglica.'" Whether the English form has any racial characters or not must be left for English students to decide. I have never seen English examples so large as anglica is claimed to be; but the size was probably not carefully meas- ured from the shell, but merely estimated by the eye. Reeve's Iconica is very unreliable in all relating to minute shells, though the figures of large species are admirable.

Var. nodosaria Boettger. PI. 1, fig. 16. May be near var. anglica, but differs by its far .smaller size. With 5 volutions the Caucasus form has relatively wider and distinctly more convex whorls, so that the aperture appears more widely ob- long. Length 3.5, diam. 1.12 mm. (Bttg., Jahrb. D. M. Ges. vi, 1879, p. 398, pi. 10, f. 10).

Var. merimeana Bourguignat. Shell lengthened oblong with obtuse apex. Whorls 6, somewhat convex, irregularly increas- ing, the upper slowly; the rest very rapidly; last two whorls very large, the last almost half the total length, descending at the aperture, rounded at base; suture impressed; outer margin arching forward. Columella short, curved, strongly retracted below, nearly reaching the base. Length 5, diam. 1.5 mm. (Westerl. ).

Shell minute, turrite-oblong, slender, polished, diaphanous, whitish, the apex obtuse; whorls 6, a little flattened, separated by a superficial, duplicated suture, the last whorl over one-third the total length. Aperture piriform-oblong; peristome acute, simple, unexpanded, the right margin slightly arching forward; columella straight, slightly truncate, margins joined by a thin callus which bears an obsolete tubercular projection on the con- vexity of the penult, whorl.

This form is probably distinct from C. acicula. It is more slender with smaller aperture, and a rather heavy callus, which forms an entering ridge or nodule below the middle of the par- ietal margin. While this structure is conspicuous in typical liesvillei, yet it varies in development, and is traceable in occa- sional specimens of C. acicula. Dr. Boettger has identified liesvillei from debris of the Kura at Borshom, Caucasus. The specimens (pi. 1, fig. 15) differ from typical acicula by the ob- solete parietal fold in the middle of the base of the last whorl,

and the less curved columella, which is only very obliquely and weakly truncate at the base. Length 5.25, diani. 1.62 mm. (Jahrb. D. M. Ges., vi; 1879, p. 398, pi. 10, f. 9.)
Var. gemmellariana (Benoit). PI. 2, fig. 28, 31. Shell elongate-cylindric, slender, polished, glossy, hyaline, whitish; spire turrited, slightly tapering, the apex mamillate; suture im- pressed, widely margined, whorls 6, subplanulate, not rapidly increasing, the last cylindric, as long as the spire. Columella subarcuate, at base narrowly and obsoletely truncate. Aperture narrow, oblong-acuminate ; peristome simple, unexpanded, acute, the margins joined by a very thin callus, right margin arching forward. Length 4.4, diam. 1.5, aperture 1.66 x 0.75 mm. (Ben.)

Benoit' s original figure is copied, fig. 31. I have also illus- trated one of several specimens before me, received from Benoit. This shows a form probably not distinguishable from liesvillei Bgt., having a slightly contracted-attenuate spire, the whorls distinctly convex, the convexity chiefly close below the suture. There is a conspicuous, spirally entering callous ridge on the parietal wall close to its junction with the columella, but other- wise the parietal and columellar margins form nearly a straight line. As usual, the first whorl increases very fast, the next whorl scarcely widens, and the last 2£ whorls increase regularly. Length 4.4, diam. 1.3 mm.; whorls 5£.
Younger shells agree better with Benoit' s description, yet even these show the trace of a callous lamella. I am disposed to place the form in the synonymy of liesvillei.
Var. tiberiana (Benoit). Vol. xix, pi. 51, fig. 5. Close to C. gemmellariana but distinct by the greater size, the upper whorls more slender and delicate, the last whorl much more swollen, and by the greater number of whorls, 6£, and the piri- form aperture. (Ben.)

Var. cristallina (Benoit). Shell turrite, whitish, smooth, translucent, the apex obtuse, spire composed of 5 slightly convex whorls separated by a well-marked suture. Last two whorls forming two-thirds the total length. Lip simple, acute, the margins joined by a callus. Aperture piriform; truncation of the coluniella strongly marked. Length 5, diam. 2 mm. Sicily : Spadafora, near Messina. (Csf-ril. cristnUind BEN., Catalogo, 1881, p. 90). Related to C. gemmelhtriami.
Var. hyalina (E. A. Bielz) PI. 1, tigs. 3, 4. The shell is very long and narrow, composed of fully 6 very slightly convex whorls, the last 4 rapidly increasing, the suture very oblique, but descending much less rapidly near the aperture. Aperture small, piriform. Columellar callus rather thin, but in certain positions its upper edge is barely visible as a slight prominence on the parietal wall. Length 5, diam. 1.25, aperture 1.7 mm.
Transsylvania: Hermannstadt, in a garden; Mediasch; Schlossberge von Vajda Hunyad (Bielz).

Bielz intended his name to replace that of acicula, but he gave a description of the Transsylvanian form, which proves to be distinct from ancula by its greater elongation. It stands close to Uesvillel, but is possibly separable by the more delicate columellar callus and the absence of a distinct callus on the parietal wall. The specimen figured was received from Bielz.
Var. uni.plimta Bourguignat. PI. 1, figs. 13, 14. Shell minute, turrite-oblong, slender, very fragile, diaphanous- whitish, crystalline, smooth; apex obtuse, mamillate, composed of 6 nearly flat or slightly convex whorls, which increase rapidly and unevenly, and are parted by an impressed, not duplicated, suture; the last whorl half the total length or more. Aperture piriform-oblong; columella uniplicate above, a little twisted, truncate at the base; peristome acute, unexpanded, simple, the right margin arching forward, columellar margin somewhat calloused. Spreading, the margins joined by a thin whitish callus. Length 4, diam. 1.25 mm. (Brit.).

The columella "a little concave, ornamented in the upper part with a lamelliform fold, and having a distinct truncation at the base " seems to be the chief characteristic of this form.
Var. aglena Bgt. PI. 1, fig. 18. Shell approaching espe- cially the C. liesvittei, but is distinguished by the mamillate summit, non-nnrgined suture, 7 whorls, and especially by the aperture, in which the penultimate whorl has scarcely any con- vexity, but forms nearly a straight line with the columella. Length 5, diam. 2 mm. Ville-au-Bois-les-Vendeuvre, Aube, France (Bgt., C. aglena, Rev. et Mag. Zool., 1857, p. 15, pi. 1, f. 3, 4; Amen. Malac., ii, p. 31, pi. 1, f. 3, 4).
Var. boettgeri Hesse. PI. 1, fig. 17. Differs from the type by the smaller size, more slender shape, angulate columella, whorls more rapidly increasing, the penultimate as high as the upper ones. Length 3, diam. scarcely 1 mm. Tinos, Grecian Archipelago, in flotsam of a small brook. Differs from liesvittei by its slimness and the shape of the columella, which has an angle in the place where there is an obsolete fold in liesvittei. (Hesse, Jahrb. D. Malak. Ges., ix, 1882, p. 332, pi. 12, fig. 8.)
Forms of Spain and Portugal.
The Iberian forms have not been figured. In a group where with the closest comparisons of specimens, species are difficult to distinguish, mere descriptions are barely worth the paper they are written on. The student will find all published in- formation below. C. acicula and C. nanodea are also recorded from the Iberian peninsula.
C. vandalitia Servain. The whorls increase regularly and rapidly; the suture does not descend much. The last whorl has a regular, median convexity, not inferior, as in belonidsea. The spire tapers gradually. The outer lip, instead of descend- ing a little below the columellar extremity, forming an angular part at the base of the aperture as in belonidsea, is on the con- trary convex and rounded to the columellar border, which is

shorter and more strongly truncate. As the increase of the whorls is regular and the convexity about equal in all there is not the contraction at the left side between the penultimate and last whorls, noticed in C. bdonidcea. The simple peristome is not thickened within, and is not patulous at the base of the aperture. Length 6, diam. 1.75, aperture 2x1 mm. ; whorls 7.

C. castroiana Locard. Shell of relatively great size, of a fusi- form, long-conic shape; spire very narrow, acuminate, com- posed of 6 slightly convex whorls, the first three increasing slowly and regularly, the following two much larger, the last whorl greatly developed, rounded at the base, three-sevenths the total length. Suture impressed, with a bordering line below. Summit small, obtuse, rounded. Aperture small, piriform, slightly over two-sevenths the total length, contracted above, well rounded at the base. Peristome simple, unex- panded and acute; right margin arching a little forward, the profile broadly arcuate; columellar border slightly sinuous, truncate, not reaching the base of the shell; the margins joined by a visible callus. Shell thin, quite solid, diaphanous, smooth, whitish. Length 7, diam. 2mm. (Loc.*).

C. ribeiroi Servain. This epecies is remarkable for the oblong- acuminate shape of the spire as far as the two upper whorls, which are cylindric; for the progressively accelerated increase of the whorls, the suture also more and more steeply descending. The last whorl is regularly long-convex. The aperture is quite excised by the convexity of the penult whorl; columellar mar- gin short, strongly projecting, strongly truncate at the base, obliquely arcuate from left to right, giving the aperture in the

C. belonidcea Servain. The upper whorls in this species are regularly elongate-convex, with a suture which does not descend much until the beginning of the last whorl, where the descent rapidly increases, the suture descending very obliquely. The last whorl is not rcgularh- convex, but is flattened in the upper part and inflated below. The long-piriform aperture is narrow above, dilated at the base; the outer margin is straight, arcuate in front. The apertural convexity of the penult whorl descends in nearly a straight line to the columella, which is short, straight, indistinctly truncate below.

" One might say that this species represents a shortened, widened aciculoldes, just as veneta seems to be a derivative of adciila. The slender shell is fusiform, but the greatest width is below the middle." The types were found at Trient with A. veneta by Professor Gredler. One example was found by Dr. Kuester at Triest.

the longer aperture, not so much receding below and less widened. The moderately increasing whorls are somewhat convex, the upper margin noticeably thickened, narrowly bor- dered. The base of the last whorl is very lightly arcuately tapering. The bend of the columella is indistinct, the trunca- tion at its base oblique. The ends of the peristome are joined by a distinct deposit. Length 5, diam. 1.33 to 1.5 mm. (Kuester, 1870).
This species was quite unrecognizably described by Jan, but it was redescribed in 1852 by Edoardo de Betta, from specimens received from Jan. I have translated de Betta' s description and reproduced his very poor figure. Kuester ably discussed the form in 1870, having specimens received from de Betta, and others collected by himself at Triest.

Figured from specimens received from Benoit, fig. 20 repre- senting the adult, 4.3 x 1.3mm., figs. 21, 22 the immature form, 3.7 x 1.2 mm. It is very similar to 0. petitiana, from which it differs in little but the smaller size, in specimens of apparently equal age. It is practically identical with C. rizzeana, though the mouth may be a thought narrower, in the specimens compared. The Madeiran C. nyctelia is conchologically not distinguishable.

From specimens before me from Benoit. this does not seem to differ materially from G. petitiana except in being smaller. I have figured a Benoit shell measuring 4.4x 1.3 mm. There is no noticeable parietal callus nodule or ridge; the outer lip is very strongly, evenly arched forward; and the last whorl descends very obliquely in the middle of its length.

Several lots, all from Benoit, are before me. The extremely thin hyaline shell has a conspicuously margined suture. The upper part of the spire is slightly contracted. The first whorl increases in width very rapidly, the next H increase but little; then the width increases rapidly again, the suture descending more obliquely. Its descent is most oblique in the middle of the last whorl, somewhat less so towards its end. The outer lip arches very strongly forward, the greatest convexity being below the middle. The parietal wall has only a thin callous film. The columella is concave, has a callous edge, and is obliquely but quite distinctly truncate at the base. Length 4.3, diam. 1.3mm.; whorls 5.

According to Mousson, there are fewer whorls than in C. acicula ; the apex is larger and more obtuse, the last whorl is more cylindric, and the remarkably narrow aperture has the free margin descending in a straight line curving towards the end of the columella and without surpassing it. The columella is but slightly concave and is obliquely truncate at the base.
The figures are copied from Boettger, and represent specimens from the drift of the Sarus river, where this species is common. He remarks that the examples vary quite noticeably in size but normally it is 4 to 4.5 mm. long, 1.12 to 1.25 mm. wide. A relative is C. subsaxano Bgt. . which perhaps may be a young form of the same species.

"By its slim shape, approaching the cylindric, its more twisted whorls, deeper suture and the appearance of the aper- ture, C. isseli is distinguished from all of ite congeners of the Alpic center."
Paladilhe probably had two species mixed in his lot of C. isseli. The description is that of a Ctzcilioides, possibly identical with Nevill's second species (Handlist Ind. Mus. p. 162), and with A. balanus of Hanley and Theobald (Conchologin,
38 OX'ILIOIDEK OF TROPICAL AMERICA.
Indica, p. 41, pi. 102, f. 10, copied in my fig. 61 of plate 4); while the figure given by Paladilhe, which I have copied, seems to belong to C. (Geostilbio.') balanus. Further investigation of the Csecilioides of Aden and India is much needed. Whether the observed differences in the columella indicate several species, or are extreme aspects of variation in a single stock, are ques- tions I can throw no light upon.
Species of tropical Asia, Went Indies, etc.
Tropical countries have a few species of Csecilioides of two groups: (1) the group of C. iota, comprising very minute species 1.6 to 2.5 mm. long, markedly cylindric, with the whorls nearly flat. All are American. (2) the group of C. gundlachi, with the shell larger, usually 3 to 5 mm., composed of convex, very obliquely coiled whorls. The columella is only quite obsoletely truncate. These groups are known as Caecilianopsis and Geostilbia.

The type lot at Amherst consists of three specimens. It is a
C.ECILIOIDES OF TROPICAL AMERICA. 39
Bubcylindric shell, obtuse at both ends, of scarcely four whorls in most examples, 4-| in the longest. The shell is clear corneous when fresh, showing the internal walls through, but it weathers to milky white. The whorls are only slightly convex, and are separated by a moderately impressed suture, margined below. The suture is at first nearly horizontal, but at the last 1£ or 2 whorls it descends rapidly, the width of the whorl progres- sively increasing. The aperture is acuminate above. Outer lip arches very strongly forward. The columella is more or less concave below, and is rather abruptly truncate above the base. Columellar callus usually moderate, but variable in thickness. Under a high power, an extremely minute spiral striation may be seen near the base. Measurements are as follows:

C. iota has been found only in Jamaica. It is readily dis- tinguished from other tropical-American species by its much narrower contour. Exact measurements which I have made of a large number of specimens from several localities show the difference in shape to be constant.
Pfeiffer's figure of this species in the Gonchylien Cabinet is very poor. It shows no columellar truncation, and hence C. iota was classed by Crosse and others in Geostilbia. Adams's type specimens, as well as numerous examples before me, have a distinctly truncate columella.

This species is closely related to C. iota, from which it differs by the stouter, more robust figure, specimens of the same length being invariably wider than iota. The general shape is slightly tapering cylindric, very obtuse at the ends. The whorls in- crease a little more regularly than in iota, the last turn of the suture being less oblique, though descending faster than the preceding one. This acceleration of the rate of descent changes the appearance of the shell and the proportionate size of aperture to total length with age, so that the addition of a whorl or even less alters the contour remarkably. The surface is lightly marked with growth-wrinkles and minute engraved spiral lines, visible only under a compound microscope. The columellar truncation is distinct, but rather weak in some examples. Two specimens from a lot taken by Gundlach are figured.
PI. 5, fig. 82: length 2.4, diam. 0.8 mm.
PI. 5, fig. 81: length 1.9, diam. 0.7 mm.
The former of these examples corresponds to the type of A. pygmcea Pfr. ; the latter, a younger shell, agrees with Orbigny's type of A. consobrina. In my opinion these two names apply to one and the same species, in slightly different stages of growth. Pfeiffer's description of A. pygmcea follows.
"A. pygmcea Ph. Shell cylindric, smooth, pellucid hyaline, the apex rather obtuse. Whorls 5, rather flattened, separated by an oblique, lightly impressed suture, the last \ the total length. Columella nearly straight, forming an angle with the belly of the preceding whorl, subtruncate at the base of the oval-elliptical aperture; peristome acute, the right margin dilated forward.

In recognizing the Mexican specimens as a race distinguish- able from the Cuban form, I am probably placing too much dependence upon a slight variation in microscopic sculpture. I merely give the facts observed for what they may be worth.

Crosse has very inadequately figured minutissima, and I have copied his figure, pi. 5, fig. 80. Figure 84, pi. 5, and fig. 68 of pi. 4, represent what I take to be Guppy's species from Barbados. The general form is as described for pygmaa] but the surface is smoother than in Cuban or Mexican shells, spiral lines being scarcely visible under the compound microscope except at the base. The columellar truncation is rather weak. Two specimens measure: Length 2.05, diam. .7 mm., whorls 5. Length 2.15, diam. .8, aperture 9 mm.; whorls 5.
With these specimens were others resembling them except that the columella is very strongly truncate at the base (pi. 5, figs. 83, 85) at all stages of growth. These may represent another species, yet I am unable to satisfactorily separate the series. The two examples figured measure: length 2, diam. .7 mm. (fig. 83); length 2.3, diam. .75 mm., whorls 5£ (fig. 85) .

The number of valid species of this group is uncertain, but several of them surely stand close to C. gundlachi. C. baldwini, C. balanus and C. mauritiana are doubtfully distinct.

Pfeiffer's description of this shell is not very good. It tapers regularly to the very obtuse, rounded apex. There are 5 whorls, very obliquely coiled, quite convex, and parted by impressed sutures. The last whorl is evenly convex. The aperture is ovate, effuse at the base; the outer lip arches forward strongly in the middle. The columella is a little concave, and near the base is obsoletely truncate. It has a rather heavy callus in most fully adult shells, which passes up over part of the parietal wall. The color is pale corneous-brown, or sometimes almost clear corneous. There is no spiral striation. Two Cuban exam- ples figured measure: Length 4.2, diam. 1.25 mm. Length 3.85, diam. 1.1, apert 1.3 mm. The figures do not well show the heavy callus upon the colunella and lower part of the parietal wall.
This is a somewhat common and widely distributed species, probably to be found throughout the Antilles. It was taken many years ago in Princeton, N. J., no doubt imported with West Indian plants. These specimens were reported as P. acicula in Binney' s " Manual." It occurred also in St. Helena, though whether it still survives there is unknown.
The New Caledonian Geostilbia caledonica is in all probability the same species, a colony having been derived from Guadaloupe or some other Antillean source. At all events I am quite

unable to see any difference in the shell. The original descrip- tion follows.
G. caledonica: PL 4, figs. 58, 59, 62.. "Shell imperf orate, fusiform-cylindric, thin, polished, diaphanous, clear-corneous. Apex abruptly rounded, very obtuse; suture hair-marginate; whorls 4, slightly convex, the last slowly descending, slightly more than half the total length. Aperture long-piriform; peris- torne simple, unexpanded, thin, not acute, slightly thickened, the margins joined by a very thin callus; columellar margin having a longitudinal, small, diaphanous, glossy internal lamina giving the appearance of a basal truncation, not reaching the base. Basal margin broadly rounded; right margin arching forward. Length 3.5, diam. 1 mm." (Crosse).

Two specimens from Noumea are drawn in figures 58, 59, 62, pi. 4. They measure 3.7 x 1.2 mm., and 3. 1 x 1 mm.
Macrospira aperta Guilding has never been described. Too poor and dissimilar outline figures were given with this name by Swainson, without locality, dimensions, or any other par- ticulars. In 1892 Mr. E. A. Smith stated that A. gundlachi and veru were equivalent to aperta; and in 1895 he identified Geostilbia caledonica, Crosse as a synonym of Megaspira (sic) aperta, from the comparison of specimens in the British Museum. In my opinion, M. aperta was not sufficiently defined by Swainson to be recognized. Its identity with C. gundlachi rests upon Mr. Smith's identification of specimens from Guilding, the locality of which is surmised to be the West Indies, but is not positively known. No description of even these specimens has appeared, and Swainson' s figures are extremely crude.

I have not seen this species, which seems to be rather common in the higher, dry parts of India, and to be known chiefly by river-drift specimens. Pfeiffer's description and the figures of Reeve and Pfeiffer indicate a shell with only weakly-truncate columella, so that one understands why Colonel Beddome should compare Geostilbia, caledonica, (which he states is identical with Indian specimens from North Canara, see Blanford, /. c. ). Nevill also refers the species to Geostilbia. In his description of <'. isseli,, Paladilhe mentions emphatically its truncate columella; yet his figure seems to represent a Geostilbia very close to balanus. Blanford has stated that isseli is identical with balanus; but so far as I can judge from the literature, there are two speciea involved. Fig. 60 is copied from Reeve's type figure. I have also copied the figure given in f^onehologia Indica, pi. 4, fig. 61. By its strongly truncate columella, this figure seems to cor- respond with the description of C. Isseli.

The shell is imperforate ovate-conic or turrite, brown or corneous-brown, glossy and usually without strong sculpture; apex obtuse. Aperture irregularly oval; outer lip unexpanded, acute or blunt; columella short, more or less deeply concave, abruptly truncate at the base.
Sole without distinct median area; no pedal margin; an outer mantle lobe on the left side. Kidney very long, band-like.
GLESSULA. 51
Genitalia peculiar (pi. 15, figs. 2); there is a feather-like gland (fig. 3) where the vas deferens enters the penis. The latter contains a short conic, perforated papilla and two of longitudinal folds. The prostate gland of the hermaphrodite duct consists of entirely separated narrow follicles, as in AchatiiKi. The spermatheca has a short duct. Uterus contain- ing several large shells with fully 2 whorls.
The jaw is very finely striate, almost smooth. Radula has about 110 teeth in a transverse row. The central tooth is very small, tricuspid; laterals with three cusps; outer marginal teeth very finely 3- or 4-cusped (G. orophila from Madras, according to Semper).
Type G. gemma Bens. Distribution, Oriental and Ethiopian regions.
Glessula was associated with " Cionelld, " (that is, the Ferus- mcidce as herein understood) by Professor von Martens in 1860. Various other authors, both before and since, have thought the group Aehatinoid, belonging to " Stenogyra' in the former wide limits of that term. We know too little of its anatomy to give a definite opinion, but the presence of a glandular append- age (appendix or llagellum) at the end of the penis is a feature unlike any Achati.nida. The homology of this appendage is not certain, however. The position of the ureter is unknown. I have been unable to obtain alcoholic material necessary for an investigation of the relations of Glesmla to Subulina, Homorua, Bacillum and Pseudoglessula.
In most (but perhaps not all) species, the lip becomes slightly blunt and smooth in fully adult shells, thereby differing from Subulina, which has an acute lip at all stages or growth.
In G. orophila, Semper found in the uterus 4 large embryos with shells having fully two whorls, and a ^mall one with a half whorl and very large caudal vesicle. Various other species have been found to be viviparous, while others bring forth globular eggs like those of SubvJina. Like that genus, also, the Glessulse reproduce before attaining full size.
Glessula has been studied mainly by specialists on the Indian fauna. Benson, W. T. Blanford, Beddome and Godwin- Austen have chiefly contributed to the literature. Blanford's
">'2 GLESSULA.
"Contributions to Indian Malacology," continued through many years of the Journal of the Asiatic Society of Bengal, contain a great mass of information on this genus, as on many others of the Indian fauna. Hanley and Theobald illustrated most of the types of Benson, among others, in their Conchologia IndicM. Finally, Colonel R. H. Beddome has recently reviewed the genus in his "Notes on Indian and Ceylonese Species of Glessula."
From the purely conchological standpoint we may be said to have an extensive knowledge of Glessula, yet various characters of the first importance have been neglected. The embryonic whorls of the types must all be re-examined and their sculpture de- Bribed. Our ignorance of the embryonic sculpture of many forms prevents any natural classification of the species. The surface of the later whorls in all the species should be examined under high power, since some species have a minute sculpture not visible with an ordinary hand lens.
No fossil species of Glessula are known to me. A few species of other genera have been referred to Glessula.
Glessula obtusa and G. erosa Blanford are species of Bacillum (Vol. xvii, pp. 1, 4).
Glessula orthoceras G.-A. is a Bacillum (I. c. , p. 2).
Glessula philippinensis Semper, of Cooke, is a Ceecilioides (this vol., p. 49).
No natural classification of the species of Glessula can be attempted until the sculpture of the apices of the shells and the anatomy of a number of representative species are studied. I have separated a group of West African forms (species 89 to 92) as a new section, Neoglessula. The species are here grouped geographically, as follows:
I. Ceylon, species 1 to 13, 34, 49, 52. II. Peninsular India, species 14 to 58.
III. Extra-Peninsular India, Indo-China, Yunnan, etc.,
species 59 to 77.
IV. Habitat unknown, species 78 to 80.
V. Sumatra, Java and Borneo, species 81, 82. VI. Eastern Africa, species 83 to 86. VII. West Africa, species 87 to 92.

Spire turrite, the apex rather obtuse, suture lightly impressed, very closely crenulated. Whorls 7^, rather flattened, the last nearly equal to two-fifths the total length, the base slightly compressed and smoother. Columella very deeply arcuate, white-calloused, obliquely, abruptly truncate. Aper- ture sinuous-semioval, white within. Peristome simple, obtuse, the right margin spreading.

The first 2£ whorls seem to be nearly smooth, but with a finely crenulate suture; then fine, distinct strise begin, strongest near the suture, weaker below. On the spire these stria? are separated into groups by occasional deeper grooves or larger striae; and more or less trace of such irregularity may often be traced on the last whorl. Under the compound microscope, the surface is seen to be very densely covered with minute granules arranged in spiral lines (pi. 6, fig. 16). These give it a charac- teristic silky sheen, unlike the smooth species. Specimens before me measure as follows, all being adults with the lip blunt.

"This little species of a group which has so many rep- resentatives in Ceylon, the Nilgherries, and the damp woody mountains of the North-eastern India, with a more slender form than A. areas nobis, is well distinguished from the allied forms by its peculiar sculpture under the lens, and by the internal incrassation of the peristome, a feature which is also observable in the species A. crassilabris nobis, from north-eastern India."

This species differs from G. ceylanica by its very much less deeply concave columella. It is a smaller and more slender shell than G. serena, which seems to be its nearest ally. The denticulation of the suture is a prominent feature. Though "live" shells, the surface is eroded in places. The whitish flecks probably will not be found on shells from stations where they are less liable to erosion.
11. G. VERUINA (Benson).
Shell cylindric-turrite, very much lengthened, dirty whit- ish, unevenly striate ; the spire gradually tapering above ; suture impressed, crenulate ; apex obtuse. Whorls 12!/2 to 13, narrow, cylindric, the last scarcely two-elevenths the total length. Aperture vertical, truncate-oval ; peristome unex- panded, acute; columella slightly arcuate.

Topotypes before me are rather dark yellowish chestnut colored, with sculpture of impressed vertical grooves. These are rather widely separated on the later whorls, but close above. Nearly two whorls at the summit are smooth. Length 8, diam. 2. 9, aperture 2.9 mm. long, whorls 6y2.
Compared with 0. p. taprobanica, this is a more slender shell, hence the whorls appear longer, and they are more evenly convex, the suture being less narrowly impressed.

Shell small, ovate, thin, costulate, glossy, pellucid, fulvous- corneous. Spire conoid, the apex rather obtuse, suture im- pressed. Whorls 5 to 6, convex, the last half the total length, slightly tapering at the base, rounded. Aperture ver- tical, semioval; peristome unexpanded, thin, acute; the right margin less arcuate; columella callous, nearly straight, very deeply arcuate, obliquely truncate, at the umbilical region appressed and depressed.

This minute form has about the size of a TornatelUna, but seems to be more strongly sculptured than is usual in that genus. The embryonic whorls are smooth, a little darker than the rest of the shell. Four specimens were taken, two of them smaller than the type, which is thought by Jousseaume to be immature.

'Full grown specimens were very rarely found by me, though young half- and three-quarter grown ones are most abundant on the Nilgiris. This and some other species cer- tainly breed before the shell attains full size or a hardened peristome, as I have taken eggs from such shells. The peris- tome differs much in mature specimens, sometimes being very thick and solid, sometimes quite thin, but, even then, firm, and not breaking or becoming jagged at the touch, which is the sign that the shell has not finished its growth. Full-grown examples of shiplayi are very like tenuispira, but smaller. It also runs nilgirica very closely, but the latter has a stronger sculpture, and is broader at the base." (Bedd.)

"The nearest ally to this species appears to be (}. tamulica ( \V. & II. Blanf.) from near Trichinopoly, which is distin- guished by greater diameter in proportion to the length, and a more regularly tapering spire. Intermediate forms may hereafter be found however.
''A specimen from the Shevroy hills near Salem in south- ern India, sent to me by Major Beddome, only differs from (i. hebes in being longer and slightly more attenuate towards the apex. It has 13 whorls." (Blanf.}
"Ten specimens received from Blanford and E vizard, col- lected near Poona, are all young, with quite unformed lip ; and all the types of hebcs in Blanf ord's collection, and the specimens in the Natural History Museum and others that I have seen, are the same. If full-grown, or nearly so, it must be a much smaller species than sliiplayi. It runs the young of that species rather closely, but the apex is gener- ally blunter. Specimens collected by me on the Shevaroys iire referred here by Blanford; they are, however, immature and appear rather to belong to fairbanki. if that species is distinct, which I doubt. When collected I took them to be young of sliiplayi. Until hebes and fairbanki are found with mature lips, they must, I think, remain doubtful species.
"Hanley's figure of hebes has the tapering apex of young shiplayi and is unlike my type of hebes." (Beddome.)

"The nearest. Nilgiri form is A. corrosula Pfr. The more cylindrical form below, the sculpture, shorter whorls etc., safely distinguished it ' (Bens.).
Col. Beddome considers fairbanki doubtfully distinct from G. liebes. Both were based upon shells not fully mature.

"The convex sides of the upper part of the spire, the shorter whorls, with the sculpture and polish of the shell, dis- tinguish it as well from the Nilgiri A. perrotteti as from the neighbouring A. notigena, which has an attenuate spire and costulate sculpture in all the whorls.

"Near A. shiplayi, but distinguished by the smaller number of whorls, more obtuse apex, etc." (Blanf.). Known from immature specimens with quite fragile lip. Col. Beddome considers that "it is very near vadalica, and has all the ap- pearance of being the young of that species."
19. G. PERROTTETI (Pfeiffer). PI. 9, figs. 9, 10.
Shell elongate-conic, the apex rather obtuse, glossy, cor- neous, diaphanous ; whorls 8, a little convex, the last half the total length, columella deeply incurved, abruptly truncate. Aperture oval, the peristome simple, acute. Length 22, diam. 9, aperture 8x4 mm. (Pfr.).

Pfeiffer's type seems to be a relatively wide, short form, with the mouth more than one-third the total length. The longer shell figured in Conchologia Indica is probably a dif- ferent species.

Benson records a variety which is more inflated, ovate- turrite, 22 x 8 mm. No locality for it is mentioned. He writes: "This shell has relations to A. chessoni in the attenu- ation of the spire towards the summit, a feature observable also in the northeastern A. tenuispira. It differs in form, size, proportions, etc. In one specimen from Bombay the attenuation of the spire is less conspicuous." Col. Beddome states that the specimens he has seen are in no way separable from tenuispira.
The initial half whorl is smooth; then very fine, close, regular vertical striae appear, continuing to the end of the embryonic shell, which consists of two whorls (fig. 9). After this, the striae are irregular, coarse ones appearing in groups,

or at somewhat irregular intervals. On the last two or three whorls the striation is still coarser, and chiefly on the upper part of each whorl, the lower part being much smoother. Specimens from Poona before me are more slender than those from Bombay, measuring 21 x 7 mm., with 10^ whorls.
The sculptured embryonic whorls show that this species is not related to G. tenuispira. I am much inclined to doubt that the specimens recorded from the Sylhet region are really notigena. They are probably tenuispira.

" In form it is remarkably similar to G. textilis W. Blanf., from the Anamallay Hills, but it entirely wants the colored markings of that species " (Blanf.). Col.

This is allied to the Nilgiri G. jerdoni Bens., but the sides of the spire are less convex, the shell being more regularly pyramidal, with a less obtuse apex. In some of the specimens of this species collected alive, but in which the animal had subsequently dried up, I found young shells. It would thus appear to be viviparous. I have observed the same circum- stance (the occurrence of young shells inside the old one) in G. cassiaca Bs. In other species of this genus I have found small round eggs with a calcareous shell, but these may be hatched, before they are deposited by the parent " (Blanf.).

The initial half whorl is smooth, the next two whorls closely, very regularly striate vertically. Then the coarser, post- embryonic sculpture begins (pi. 10, fig. 4). The striation is rather sharp but uneven, and the striae are strongest at and near the suture, decreasing downwards. It resembles G. noti- gena somewhat, but the early whorls are not attenuated, and there are 2y2 embryonic whorls.
Col. Beddome remarks: " I found the smaller variety very abundant on the top of the Myhendra Hill (Ganjam). The larger variety, found near Calcutta and in central India, and well figured by Hanley, is a rare shell. It has a shorter and blunter apex and fewer whorls than G. vandalica, but speci- mens of that species sometimes do duty for it in collections."

Reeve's second locality, Colombo, Ceylon, was probably due to an erroneous identification. Col. Beddome omits the Nil- giris from his list of localities.

A specimen evidently near subjerdoni, but purchased as G. jerdoni, and said to be from the Nilgiris, is figured, pi. 12, fig. 16. Below the suture there are vertical grooves, strong and regular on the shoulder, but rapidly weakening down- ward. The lip is rather thick and whitish-edged. It is a wider shell than G. p. taprobanica, which seems to be closely- related. Length 9.2, diam. 3.9, aperture 3.25 mm. ; whorls 7>

" This is one of the group of small Indian Achatinas com- prising A. gemma Bens., and A. scrutillus B. From these two shells the present species is distinguished by its conical spire with straight and not convex sides, its paler color and sculp- ture.

"This shell resembles in form A. oreas Bens., but is dis- tinguished from that and 'all other allied species by its stronger sculpture. Possibly the two varieties should be ranked apart, as there is considerable difference between them. A third form, shorter and more tumid, occurs near Poona. As other intermediate varieties probably exist, I prefer for the present classing all in one species, but it may hereafter be desirable to distinguish them." (Blanf.)
The figure in Conchologia Indica, which I have copied, does not agree very well with the description, but it is said to represent the type specimen.

"Full grown shells collected in the Teesta Valley near Darjiling, and in N. Canara, measure 44 mm. in length, and have 14 whorls" (Beddome). G. baculina and G. pertenuis are considered to be specifically inseparable from G. tenui- spira by Col. Beddome, a conclusion supported by the speci- mens before me. The presence of this trans-Gangetic snail in the North Canara Hills is remarkable, if indeed, the Canara shells are really of the same species.

Khersiong, Himalayas of Sikkim.
"This species appears to have escaped the notice of all previous collectors in Sikkim; it was found in association with its near ally G. tenuispira Bens., by Dr. Stoliczka during a recent visit. It is easily distinguished from the latter species by its slenderness, (the diameter being % of the length) and the comparative narrowness of the whorls; moreover by the form of the columella, the lower part of which is bent abruptly almost at right angles with the slope of the inner lip; while in G. tenuispira, G. erosa, and other allied forms, the curvature is at the utmost obtuse. Specimens, the shell of which has been slightly weathered, show fine spiral mark- ings, but these are not visible unless the shell has become somewhat opaque. The animal is dark leaden grey, some- what paler at the sides of the foot." (Blanf.)
"This is, I believe, only a more slender form of tenuispira, as I have specimens intermediate in breadth ; as to any differ- ence in the columella, some of my specimens of tenuispira have the lower part more bent than in any of the supposed baculina " (Beddome).

A much more slender species than A. tenuispira Bens., (a variety of which also abounds in parts of Pegu), though there are signs of a passage. The present appears to replace A. tenuispira in Arakan and Bassein. Mr. Benson, to whom I sent a specimen, observes that it is intermediate between A. tenuispira and A. hastula Bens. (Blanf.)
Col. Beddome gives the localities, Assam; Arakan; Garo and Naga Hills; Burma. He remarks that " Blanf ord's types and all the specimens I have seen of this, are young shells, with fragile, unformed lips. They fit well with young of tenuispira. Blanford himself mentions that there are signs of a passage, and it would certainly not be advisable to consider it a good species without seeing specimens with adult lip."
60. G. NAJA 'Blanford' n.sp. PI. 12, fig. 10.
Shell slender, turrite, thin, yellow-corneous, glossy, weekly striatulate, and having vertical grooves at unequal intervals; this sculpture is most evenly developed just below the suture. Under the compound microscope glimpses of ex- cessively weak close spiral granule-lines may be seen in places. Outlines of the spire nearly straight, a trifle contracted near the apex. Whorls 9*4, moderately convex, separated by a deeply impressed simple suture. Aperture a little oblique; outer lip thin; columella rather long, regularly concave, truncate at the base.

"This species is an elongate and larger form of Glessula crassilabris Bs., of which G. pyramis is a closer variety; but its much more elongate form and stronger striation make it a good connecting species with G. butleri described further on. The form from the Lukah Valley is a tumid departure from the type figured. Alt. 0.75, major diam. 0.38 inch. Alt. 0.65, major diam. 0.35 inch."
"I look on all these species as properly varieties, and G. crassilabris, very abundant in all the grass country of the Khasi Hills, may be taken as the type; a difference in eleva- tion and condition of habitat, from damp dark forest to hot grassy slopes, having produced modifications of form." ( Godwin-Austen. )
Figs. 15, 16, are copied from Godwin- Austen 's originals. A typical specimen, length 18.75, diam. 7.8, aperture 7.5 mm., whorls slightly over 7, is shown in figs. 13, 14. The em- bryonic whorls are closely and finely striate vertically, as in G. notigena; hence the species has no affinity to G. crassilabris. It is a much less robust shell than G. crassilabris, and less polished ; and on the last whorl there are traces of fine spiral striation, as shown in fig. 13. The sculpture of the later whorls is irregular; there seem to be unequally separated grooves, with finer strige and grooves in the intervals, but quite unequally developed. The suture is crenulate. On the last whorl or two some traces of spiral striae appear, in places.

The outer lip is a little sinuous, being retracted above; it is moderately thickened or obtuse.
Col. Beddome considers this species identical with G. facula.

Length 18, diam. 8, aperture 7.5x4 mm., whorls 8 (Pfr.).
The shell is ovate-oblong, yellow. The embryonic whorls are smooth, a little over two. Subsequent sculpture consists of rather close grooves, most prominent at the suture, which is rather deeply impressed, though the whorls are only moder- ately convex. The suture descends a little near the lip. The aperture is rather small, outer lip decidedly obtuse, thick- ened, its rounded edge bicolored, white and yellow. The outer lip is slightly retracted in the upper part. Length 20.5, diam. 9.5 mm., whorls 6% (fig. 15).

Godwin-Austen (1875) considered pyramis, butleri and il- lustris as subspecies of G. crassilabris. The latter is de- cidedly more robust than illustris, which belong to a differ- ent group ; pyramis and butleri are both more elongate shells.

This species closely resembles Glessula peguensis Blanford, but is less convex, that is, more slender, and a thicker texture ; it can also be easily distinguished by the characteristic, crowded, well-developed, nearly perpendicular, longitudinal striation, varying slightly in direction on each whorl, much as in many species of Pomatias. The columella also is peculiar. Type in Indian Museum, Calcutta." (Nevill.)

VII. West African species.
Two quite distinct groups of Glessula are represented in West Africa. The group of G. l&vigata has substantially the shell-structure of Indian Glessulae. The shell is smooth throughout (species 87, 88). In the group of G. paritura the post-embryonic whorls are finely rib-striate (species 89 to 92).
Group of G. Icevigata.
The central teeth of G. Icsvigata are narrow, not half as wide as the adjacent laterals. There is a well developed but not overhanging cusp. The laterals are quadrate, tricus- pid, with overhanging cutting-points on all the cusps. Middle cusp longer than the basal plates. There are about 8 laterals, then one or two transitional teeth, followed by the marginals, also of the tricuspid type (pi. 15, fig. 9). The jaw (pi. 15, fig. 10) is very minutely plaited, serrate on the cutting edge, at least in places.

Morelet, who was the first to record a locality for this species, thinks that it must originally have been found nearer the coast, as it is unlikely that any earlier traveler had visited the remote solitudes where Dr. Welwitsch found it.
The whorls are smooth except for weak growth-striee, and are parted by a linear suture which is transparent-margined below. The fifth whorl appears disproportionately wide. The spire tapers rapidly near the obtuse apex, but much more slowly throughout the greater part of its length. The ex- cision at the base of the columella is not very deep. Ex- amples measure:

Achatina paritura GLD., Proc. Bost. Soc. Nat. Hist, iii, 1850, p. 196; Otia Conch, p. 208.— PFR., Monogr. iii, 491. — PETIT, Journ. de Conchyl. ii, 1851, p. 269, pi. 8, f. 7. — Honwrus p., KOBELT, Conchyl. Cab. p. 92.
This species is viviparous. The summit is semiglobular ; first 11/2 whorls smooth in adults, but in young shells they show sparse engraved spiral lines; then vertical grooves ap- pear below the suture, short and widely spaced at first, but gradually lengthening and becoming 'Closer, so that at the end of 2y2 whorls they reach nearly to the suture below, and become so close that the sculpture may be described as rib-

striate, the riblets smooth, rounded, and about equal to the intervals. On the face of the last whorl there are five or six riblets in one millimeter. The riblets weaken or disappear almost abruptly at the periphery of the last whorl, leaving the base and a very narrow band above the suture almost smooth. The columella is formed just as in the Indian Glessulae, being deeply concave, thickened with a white callus, and abruptly, deeply truncate at the base. The shell is translucent whitish under a very thin pale yellow cuticle. A specimen of the ordinary size measures, length 20.3, diam. 8.8, aperture 8.3 mm. ; whorls 6^.
An embryonic shell, shaken out of an adult, is oval, 4.7 mm. long, with 3 whorls. There is a distinct umbilical slit behind the columellar callus (pi. 14, fig. 19).
90. G. BRETIGNEREI Chaper. PL 14, fig. 20.
Shell thin, transparent, of a light gray-olive tint; shining, though sculptured with very regular, crowded striae of growth, well-marked from the end of the second whorl. Spire of 6 or 7 whorls, very regularly conic after the second whorl. Aperture oblique; columella strongly inflexed towards the interior of the aperture. No umbilicus. Length 30, diam. 11 to 12 mm. (Chaper}.

This species differs from G. paritura only by its larger size, so far as the published account goes. Kobelt confused the name with that of Corbula assinicnsis, which occurs on the next page of Chaper *s paper.
91. G. MALAGUETTANA (Rang). PI. 14, fig. 15.
Shell elongate, conic, thin, subdiaphanous, very minutely longitudinally striate, brown-buff. Apex obtuse. Aperture oval, the columella arcuate, truncate; lip simple, acute.
HO WEST AFRICAN GLESSULA.
Length 15 to 20, diam. 8 to 9 mm. Animal dirty buff, 25 mm. long. (Rang).

This shell, according to Rang, is long, conic, thin, almost diaphanous, very finely and regularly striate; the very thin cuticle covering it is of a dirty yellowish brown, resembling that of Subulina striatella. The summit is obtuse, and its whorls, 6 in number, are quite rounded. The aperture is oval, little oblique. The columella is very concave and trun- cate in front; the right margin is straight and thin, fragile and acute. Deshayes gives the dimensions 22 x 8 mm. The systematic position is unknown, and it may prove to be a Pseudoglessula. The spire is more slender above than in G. paritura.
92. G. SERICINA (Jonas). PI. 14, figs. 13, 14.
Shell ovate-turrite, rather thin, longitudinally closely pli- cate, pellucid, glossy, straw-colored. Spire turrited, the apex very obtuse. Whorls 6 to G1/^, convex, the last about three- sevenths the total length, obsoletely angulated in the middle, smooth below the angle. Columella very arcuate, highly and widely truncate, the aperture suboval. Length 17, diam. 7 mm., aperture iy2 mm. long, 4 wide in the middle. (Pfr.)

This snail has a beautiful appearance from its very regular, pretty and strong striation, and its silky luster. (Jonas) .

OLEACINID^E.
SPIRAXIS BLANDIANUS Pils. New name for Spiraxis blandi Crosse & Fischer, (Journ. de Conch. 1877, p. 271; Miss. Sci. Mex., Moll., i, p. 616; Manual I, p. 52, XIX, p. 27), not Spiraxis blandi (Crosse), described as Ravenia c., Manual XIX, 19, 20.
VARICELLA DISSIMILIS Pilsbry. Vol. XIX, p. 105, pi. 17, f . 10, 11.
New name for Achatina similis C. B. Ad. 1850, not A. similis Boissy, 1848.
The specimen figured and described (XIX, 105) by me becomes the type of this species.
VARICELLA DISSIMILIS LONGIOR Pils., new name. V. similis longa Pils. (Man. Conch. XIX, p. 106), being a homonym of V. costulata longa (t. c. p. 68), may be changed to Varicella dissimilis longior.
VARICELLA SIMILARIS SLOANEANA Pils.
New name for V. s. mandevillensis Pils., (XIX, p. 107), preoccupied on p. 70 of same volume.
STREPTOSTYLA LIMNEIFORMIS CHIAPENSIS Pils. Vol. XIX, p. 159.
New name for Spiraxis parvula Pfr. 1856, not of Chitty, 1853.
EUGLANDINA FUSiFORMis Pfr. Achatina /"., Pfr. P. Z. S. 1845, p. 75 ; Monogr. ii, 292 ; Man. Conch. XIX, 188, is a homonym of Achatina lubrica var. fusiformis Picard, 1840. See Vol. XIX, p. 320. The Mexican species should probably stand as E. binneyana.

112 APPENDIX.
ACHATINA NYSTIANA Pfr. Shell fusiform-oblong thin, smoothish, very delicately striatulate, pellucid, glossy, flesh- colored. Spire long, slender, the apex obtuse, suture thread- margined, whorls 6l/2, a little convex, the last about three- sevenths the total length, tapering at base. Columella very lightly arcuate, the base shortly and horizontally truncate. Aperture scarcely oblique, oval-elliptical, peristome simple, thin. Length 47, diam. 12, aperture 16y2 x 6 mm. Habitat unknown, Mus. Cuming (Pfr., P. Z. S. 1855, p. 100; and as Oleacina n., Monogr. iv, 632). Evidently an Euglandina.
GLANDINA CRENULATA Sow. Ant., Pfeiffer. Shell fusiform ovate, rather solid, reddish-corneous, glossy; spire with the apex obtuse. Whorls 6~y2, a little convex, the last descending, shorter than the spire; suture margined and most minutely crenulate. Aperture dilated below, columella subarcuate, strongly truncate; peristome simple. Length 24, diam. 11, aperture 11 mm. long. Central America. (Pf?-, Symbolae ad Hist. Hel. ii, p. 59, no. 273, 1842, from spec, in coll. An- ton, recorded without description in Anton's Verzeichniss as Achatina crenulata Sow.? p. 44, no. 1595. "Achatina crenu- lata (Sowerby?) Anton," PFR., Monogr. ii, p. 285). Seems to be unknown to monographers of the Mexican fauna. It is not recognizably denned.
POIRETIA.
A list of species referable to this genus was given in Vol. XIX, pp. xxii-xxv. The preparation of an index of Achatina etc. has shown that several names are homonyms and require change, as follows. POIRETIA KLEINIANA Pilsbry, n. n.
New name for Achatina elegans Klein, Jahreshefte des Vereins fur vaterlandische Naturkunde in Wurttemberg, ix, 1853, p. 214, pi. 5, f. 11, not A. elegans C. B. Ad. 1849. Cf. Vol. XIX, p. xxiv.
POIRETIA INPLATA Reuss, (XIX, p. xxiv). Add the synonym: Olandina (Achatina) antiqua KLEIN, Jahresh. Wiirttemb. VIII, p. 162, pi. 3, f. 9, 1852.
APPENDIX. 113
POIRETIA ROUISIANA Pilsbl'y.
New name for Oleacina teres Rouis, Sandberger, Land und Siisswasser Conchyl. der Vorwelt, p. 232, pi. 13, f. 26 (1872), not Oleacina teres Pfr., Malak. Bl. 1866, p. 140. Eocene, Buxweiler.
POIRETIA WOODI Pilsbry.
New name for Bulimus convexus 'Edwards' S. V. Wood, 1877 (Vol. XIX, p. xxiii), not of Pfeiffer, 1855 (cf. vol. XI, p. 216). The generic position of this Oligocene form of the Isle of Wight is uncertain. Photographic figures are re- produced by Taylor, Mon. Brit. Land and Freshwater Moll. ii, p. 29, f. 46, 47.
POIRETIA MILLERI Pils.
New name for Glandina ovata Miller (Vol. XIX, p. xxiii), not Glandina truncata var ovata Dall.
ACHATINA NYIKAENSIS Pils.
New name for A. fragilis Smith, 1899, Vol. XVII, p. 63. Not Achatina fragilis Deshayes, An. s. Vert. II. ARCHACHATINA MARQINATA EDUARDI Pils.
New name for Achatina marginata var. gracilior Martens (Manual XVII, p. Ill), not Achatina gracilior C. B. Ad. 1850. ARCHACHATINA PURPUREA (Gmel.) Vol. XVII, p. 144.
Add the following synonyms: Achatina purpurascens G. FISCHER, Museum Demidoff iii, p. 224 (1807). Achatina erythrostoma SWAINSON, Bligh Catal., Appendix p. 14 (1822), based on Martini and Chemnitz, IX, f. 1017, 1018.
HELIX (COCHLITOMA) CANTHERIATA Fer., Prodr. p. 49, no. 340 is a nude name. Ferussac refers to the figure of a Phasianella as perhaps illustrating it. Habitat unknown.
ACHATINA HYALINA Anton. " Oval-conoidal, 5 convex whorls with deep suture, last whorl two-fifths the total length ; transparent, glossy, yellowish-gray, finely striate, imperfor- ate. Aperture long-oval, peristome acute ; columella strongly

Pfeiffer renamed the species Achatina antoniana, Mono- graphia Hel. Viv. ii, p. 285 (1848), the original name being preoccupied. It is probably a Leptinaria, but it has been recognized by no author since Anton.
BOCAGEIA (PETRIOLA) ANJUANENSIS Pils., n. n.
New name for Achatina cornea Morelet 1877, not of Bru- mati, 1838. Type is the shell described in Man. Conch. XVIII, 189, 190, and illustrated in fig. 23 of plate 57. Rumina decollata paiva Lowe. Vol. XVII, p. 213, 214.
It should be observed that the names lanceolata, cornea, maxima, flammulata and decussata were already in use in Bulimus, hence must be dropped as homonyms in Rumina, even if the races denoted are valid, which seems doubtful.
FEEUSSACIDJE.
FERUSSACIA TERVERIANA Pils., new name for Achatina terveri Bgt. 1859 (Vol. XIX, p. 259, no. 48) ; not A. terveri
Boissy, 1848, a species of Poiretia.
FERUSSACIA HYPSELIA Pilsbry.
New name for F. producta Lowe 1852, not of Reuss, 1849. See Man. Conch. XIX, p. 275. The type of F. hypselia is the specimen figured, Vol. XIX, plate 39, figs. 24, 25.
ACHATINA BUCCINULA Grateloup, Actes Soc. Linn. Bor- deaux X, 1838, p. 122, pi. 4, f. 25, 26, from Dax, seems to be a Miocene species of Hohemvartiana.
BULIMULnXE. G-enus HEMIBULIMUS Marts., Vol. XII, p. 184.
Mr. E. A. Smith (Proc. Malac. Soc. London VII, p. 313) has called attention to my failure through oversight to in- clude Achatina dennisoni Reeve in the Manual. He has also discussed the characters and synonyms of that and other
HEMIBULIMUS. 115
species of the group Hemibulimus, correcting various errors which, by reason of the scarcity of material, had been per- petuated from author to author.
The relation of Hemibulimus to Liguus is not very close and I now doubt the propriety of including them in one genus. Except in the structure of the columella, Hemi- bulimus is very similar to Porphyrobaphe.
1. HEMIBULIMUS EXCISUS (v. Marts.) Vol. XII, p. 185, pi.
36a, figs. 31-34.
Popayan, Colombia, at 2400 meters. Type species of Hemi- bulimus. While evidently related to dennisoni, it is prob- ably distinct, at least varietally, as Mr. Smith believes. In Vol. XII I followed Professor von Martens in uniting excisus and magnificus.
2. HEMIBULIMUS DENNISONI (Reeve). PI. 40, fig. 1.
"Shell fusiformly ovate, spire rather acuminated, whorls 6, somewhat rudely faintly plicately striated, decussated with fine impressed striae. Apex somewhat papillary. Columella arched and twisted, attenuately truncated. Pale brown, varie- gated towards the apex with darker brown, last whorl un- spotted, encircled with a pale obscure band, columella pink- ish." (Reeve}.

Achatina dennisoni REEVE, Conch. Icon, v, pi. 9, f. 32 (March, 1849). — PFR., Monogr. iii, 486. — Liguus (Hemibuli- mus) dennisoni (Reeve) E. A. SMITH, Proc. Malac. Soc. London vii, 1907, p. 314, 313. — Achatina magnified, REEVE, op. cit. pi. 9, f. 33, not of Pfeiffer. — L. magnificus (Pfr.) PILSBRY, Man. Con. xii, pi. 36 a, fig. 30 (not the description).
Reeve described and figured a shell from the Dennison col- lection. The present location of the type is unknown. The figure (copied on pi. 40, fig. 1) shows a pale red-brown shell with decidedly attenuate early whorls, a brown-spotted sub- sutural band, and two other pale bands on the last whorl. The parietal wall is purplish but not black. The aperture is markedly acuminate above. Judging from the description
116 HEMffiULIMUS.
and figure, the sculpture is not so strong as in the following form; yet it must be remembered that the sculpture is usu- ally minimized in Reeve's figures of Achatina.
H. D. CARUS Pils., n. var. PI. 40, figs. 2, 3, 4, 6.
The shell is elliptic-ovate with a rather slender spire and obtuse apex; solid and strong. Nearly 2y2 smooth, convex whorls form the semiglobose embryonic shell. The next whorl is lightly striate, near its termination the surface becomes minutely plicate and spiral grooves appear ; on the next whorl it is closely and finely plicate, the plicae cut by several (usually 5 to 7) spiral furrows, which appear as if scratched in a plastic surface. On the last whorl the fine plicae become weaker, irregular, often more or less obsolete towards the end of the whorl; there is more or less indistinct malleation, and some irregularity due to former growth-arrest periods, marked by dusky streaks, of which there may be one to four or more on the last whorl. The aperture is elliptic-pointed, outer lip obtuse, more or less thickened, expanded or effuse towards the base. Columella arched, usually very deeply, but sometimes only moderately, its lower portion colored like the outer lip; base truncate, parietal callus glossy black, overlaid with blu- ish inwardly. Color as follows :
(1) Ground-tint yellow, fading towards the apex: (a) brown spots below the suture appearing on the first post- embryonic whorl, becoming broad, more or less fulgurate stripes on the penult, and next earlier whorls; last whorl showing three narrow equidistant bands and an irregular mottling of the yellow ground, elsewhere olive and brown of varying shades; outer lip and lower half of columella edged with vermilion. (&) intermediate whorls of the spire marked with narrow, close, wavy brown streaks; antepenult, whorl with some subsutural spots, last whorl without bands, irregu- larly streaked with dull green on a greenish yellow or light yellow green ground; outer lip and basal half of columella bright ochre.
(2) Ground-tint reddish, (c) nearly uniform ochraceoua reddish, the red predominating on the earlier whorls; outer
HEMIBULIMUS. 117
lip dull red, fading to pink in the throat, (d) first post- embryonic whorl -with subsutural spots, next whorl or two closely streaked with dull red-brown ; last whorl of a muddy olivaceous shade, with some darker brown streaks; lip with a narrow red edge and dark submargin.
Length 68, diam. 32 mm. ; aperture 37.5 mm. ; whorls 6*4.
Length 65, diam. 34.5 mm. ; aperture 38 mm. ; whorls 6.
Length 65.5, diam. 31 mm.; aperture 37 mm.; whorls 6.
Length 62, diam. 29.5 mm. ; aperture 33 mm. ; whorls 6^.
Colombia: Quilichao, Cauca Valley, 5,500 ft. elevation.
Achatina magnified, REEVE, Conch. Icon. V, pi. 9, f. 33. — L. magnificus Pfr., PILSBRY, Man. Conch. XII, pi. 36a, f. 30. Not A. magnified Pfr.
This form differs from Reeve's figure of A. dennisoni by its intensely black parietal callus, and the shape of the aper- ture, which is wider, less acuminate above, the outer lip be- ing arcuate and not straightened near the insertion.
Reeve's figure 33, (copied in Manual XII, pi. 36a, fig. 30) represents a form differing from this race only in size, as Mr. E. A. Smith has pointed out. In the Manual I fol- lowed Reeve's error in referring to it as an illustration of Achatina magnifica Pfr.
3. HEMIBULIMUS MAGNIFICUS (Pfr.). PI. 40, fig. 5.
See Vol. XII, p. 185, where a translation of Pfeiffer's description is given. From the reference-paragraph there given the reference to Reeve's figure should be excluded, and the following added: Liguus (Hemibulimus) magnificus (Pfr.), E. A. SMITH, Proc. Malac. Soc. London VII, 1907; p. 314, fig. of type. This species seems to be known only by the original specimen, said to be from Quito. Mr. Smith's figure of this is copied on my plate. The specimens obtained •by Lehmann in southern Colombia may have been H. dennisoni.
ACHATINA MONILE Swainson. "Shell very finely reticu- lated, whitish with waved stripes, and transverse bands of chestnut spots ; basal volution subventricose ; spire produced,

This seems to be some such shell as Oxystyla ferussaci, or some of the forms represented on plate 17 of vol. XII ; yet the "apex papillary" recalls Pseudotrochus (Perideris) .

PARTULID^E. 155
Family PARTULID^E Pilsibry.
Partulidce PILS., Proc. Acad. Nat. Sci. Phila. 1900, p. 564.
Orthurethra in which the kidney is triangular, equal to the pericardium in length. Genitalia of the haplogonous type, the penis without an appendix. Shell Buliuioid, with the outer lip expanded or reflexed in known forms; the eolumellar lip reflexed, curving into the basal margin, simple or nodu- lous; parietal wall often dentate, but the aperture never has entering lamellae
Jaw very thin, formed of many narrow flat plaits, converg- ing downward towards the middle. Radula broad; the cen- tral tooth is not much smaller than the laterals, and has a long middle and small side cusps; lateral teeth with the mesocone long, ectocone well developed, but no entocone; marginal teeth oblique with three cusps directed outward, the inner one largest.
Distribution entirely insular, confined to high islands of the southern and western Pacific. Nearly all the species are arboreal, living on trees and bushes, but some species of Raiatea, Tahaa, Tahiti and perhaps the Caroline Islands, are terrestrial.
This family is co-extensive with the following genus.

156 PARTULA.
Soft anatomy of Partula.
The first anatomical observations on Partula were by Ferussac, who discovered that these snails are viviparous. He erroneously states that they have no tentacles, only the eye- pedicels. The next work was by Heynernann, who figured the teeth of P. Urata.
The following species of Partula were dissected by Dr. C. Semper (Reisen im Archipel Philippinen, Landmollusken, pp. 158, 159) : P. canalis semilineata, recluziana, Urata (pi. 17, f. 18, jaw), hyalina (pi. 16, f. 21, genitalia), lineata, otaheitana (pi. xii, fig. 21, genitalia), vanikorensis (pi. 17, f. 17, teeth) . P. lineata was probably not correctly identified.
In 1875 (Proc. Acad. N. S. Phila., p. 244) Mr. W. G. Binney examined the anatomy of numerous Raiatean species : P. fusca (pi. 19, f. 9, genitalia), citrina, planilabrum ab- breviata, umbilicata (pi. 19, f. 7, genitalia), bilineata (pi. 19, f. 10, genitalia), amanda (pi. 19, f. 4, teeth), virginea (pi. 19, f. 8, genitalia, f. 11, jaw), and gracilis, besides several unidentified species. Some of the same information is re- peated in Annals, of the N. Y. Acad. Sci. iii, p. 127.
I have examined more or less fully P. rosea, P. varia, P. arguta and some unidentified Raiatean species received with- out the shell.
We have therefore some knowledge of the soft parts in species of the sections Partula, Leptopartula, Samoana, and Thakombaua, inhabiting the Society, Samoa and Fiji groups.
Animal externally like that of Bulimulidcu or Helicidcs; blunt before, the tail long, gradually tapering. There are no pedal furrows, and the sole is undivided. Dorsal grooves weak, but the genital furrow is well developed. Genital pore behind the right tentacle, as usual. The labial processes are rather large. The mantle has very small right and left lobes. The tentacles are as well developed as usual in land snails (pi. 32, fig. 10, P. canalis}.
Garrett writes: "The examination of the animals of the various species has convinced me that they possess no re- liable external features that will aid in their determination.
PARTULA. 157
The coloration in all the species varies from pale cinereous, through all the intermediate shades, to black or dusky slate. The 'arboreal species are generally lighter colored than the ground species, and have a more expanded creeping-disk. The animals of P. arguta, annectens, turgida and attenuata, have the ocular tentacles longer and more slender than the other species, and the exudation of mucus is much more copious and more viscid or tenacious than usual, resembling in that respect the same difference as exists between the typi- cal Helices and the arboreal Naninae. "
The pallial organs are characterized by the short, more or less triangular kidney, with a direct ureter which does not extend to the collar, and opens by a lateral pore. The peri- cardium is as long as the kidney. The surface of the lung shows no visible venation. It is densely peppered with light dots (probably calcareous) arranged in irregular lon- gitudinal lines. In P. arguta these light dots are present in spots and stripes (pi. 42, fig. 4), but in other species examined they are equally and densely spread over the whole surface.
In P. rosea (pi. 42, fig. 5, x 3) the kidney is very short and strictly triangular. According to Semper, that of P. canalis seems to be of the same form. In P. arguta (pi. 42, fig. 4) the kidney is relatively larger, and the pericardium lies parallel to its longer axis. The ureter also is longer. In an undetermined Raiatean species (doubtless of the re- stricted section Partula) the kidney approaches the band- like type (pi. 42, fig. 6), yet it is somewhat triangular, and equal to the pericardium in length. This is probably the prevalent shape of kidney, since Semper mentions that all the species examined by him except canalis had the kidney, "bandformig. " In most of the subgenera the kidney is unknown.
The alimentary canal is of the usual four-folded type. There is a fusiform crop (pi. 42, fig. 5).
The jaw is very thin and transparent, varying from slightly arcuate to horseshoe-shaped, similar to that of Drymczus and Zaplagius, formed by the union of many narrow delicate
158 PARTULA.
plates, which converge towards the middle, so that there are short plates where the two series meet (pi. 42, fig. 1 jaw of P. lirata, after Semper; fig. 2, central portion of jaw of P. gracilis Pse., after Binney).
The num'ber of plates on the two sides is unequal, there being in lineata 27.36, in recluziana 34.38, in otaheitana 40.50 according to Semper.
The radula is broad. The teeth form thrice bent transverse rows, as shown in pi. 15, fig. 11, a half row of teeth of P. lirata. The central teeth have the usual quadrate basal plates. In P. amanda, P. rosea, P. varia etc. the length of the basal plate is about twice its width in the middle; the middle cusp is long, reaching to or over the posterior border of the basal plate. Side cusps represented by cutting-points, only. The lateral teeth are larger, with the mesocone longer, outer cusp well developed with a strong cutting-point (pi. 43, fig. 1, P. varia huaheinensis Garrett; fig. 2, P. rosea Brod.). There are 11 lateral teeth on each side in P. rosea and planilabrum; 10 in abbreviata, amanda, otaheitana; 8 or 9 in varia, umbilicata, virginea, bilineata, kyalina, lineata, recluziana, canalis; 5 in gracilis. The marginal teeth are peculiar in form, having a long, curved basal plate and 3 cusps, the inner largest, the other two directed outward (pi. 15, fig. 8, 13th to 15th teeth of P. rosea}. They are numer- ous, over 120 in P. virginea.
The Fijian P. lirata differs from the Society Island species examined by Binney and myself by having the central and lateral teeth shorter and wider, the central scarcely longer than wide. There are 7 lateral and over 50 marginal teeth, the latter of typical shape (pi. 15, figs. 11, 12, P. lirata after Heynemann) .
The radula has been examined in numerous species from the Society, Fiji and Samoan Islands, 'by Heynemann, Binney, and Semper. I have examined it in P. rosea and varia.
Genitalia (pi. 43, fig. 5, P. rosea). — The penis is well de- veloped. It is more or less distinctly contracted near the distal end, which is swollen. Internally the lower portion is
PARTULA. 159
Coarsely wrinkled, the upper portion densely granulose and coarsely plicate. The retractor muscle is terminal. The vas deferens opens below a papilla situated at about the lower third of the granulose portion ; it is therefore not terminal on the penis. It is superficially bound to the penis, to the vagina and the basal part of the spermatheca, then free as far as the upper end of the oviduct, where it is again adnate for a short distance. The ovisperm duct is strongly knotted, as usual. The 'basal part of the spermatheca-duct is much swollen in P. rosea and P. fusca, the distal end tapering; but in P. bilineata (pi. 43, fig. 3, after Binney) umbilicata, virginea, otaheitana and hyalina the spermetheca is oblong, obtuse distally, and seated upon a slender duct. In all the species which have been examined the duct is short.
Reproduction seems to 'be ovo-viviparous. The upper part of the oviduct contains oblong egg-capsules having a cal- careous shell, which lower down in the oviduct becomes dis- solved or is consumed by the embryo. From one to five eggs or young are found in one individual.
Free muscles: — In P. rosea (pi. 43, fig. 4). The pharyngeal retractor is free to its proximal insertion. At about the middle of its length the left ocular and tentacular retractor band joins it, and a little farther out the anterior pedal re- tractors branch off. The broad posterior pedal retractor (tail retractor or columellar muscle) remains united far forward with the right ocular and tentacular retractor, which gives off a group of small anterior pedal retractor muscles. The right ocular band passes between the male and female branches of the genitalia.
This muscle system differs from that of Achatinella dolei chiefly by the union of the right ocular with the tail retractor. In Achatinella both ocular bands are free.
Relationships of Partulidc?.
This family is one of the most sharply defined in the Orthurethra. By its short kidney, about equal to the pericardium, it differs conspicuously from the Enidce,
160 PARTULA.
Ferussacidce, Amastrida and Achatinellidce, all of which have the kidney very long, far exceeding the pericar- dium. For comparison I figure the pallial region of Ena reiniana (Bidiminus reinianus Kob.), pi. 42, fig. 3, x 2. In the genitalia, the Partulida are remarkable for the absence of an appendix, the penis being simple. This organ is pres- ent and highly developed in all the other families. The vas deferens is practically free from the oviduct, its adhesions being merely superficial. This is a somewhat unusual con- dition, and where found it seems to be associated with vivip- arous reproduction. The shell is rather characteristic; in form some En-idce are similar, yet the spirally striate em- bryonic whorls are unlike that family, and are an invariable feature of Partulidce, though occasionally this sculpture is lost by wear in adult or old shells. This is not in itself a feature of much importance, yet so far as I know, there is no other Bulimoid snail with an expanded or reflexed lip which has spirally striate embryonic whorls.
From these comparisons it will be seen that the Partulidce stand somewhat isolated. There is no family of Bulimoid or Achatinoid Orthurethra which can be said to be nearer than any other to the Partidida, so far as present informa- tion goes.
Hybridism.
In dealing with Society Island species both Mr. G-arrett and Dr. Hartman have called attention to certain specimens of intermediate character which they looked upon as hybrids between species commonly considered to be distinct. Garrett writes as follows: " Hybrids between P. elongata and P. tceniata, and between P. garretti and P. thalia, are so com- mon where those species come in contact, that I am inclined to believe they possess a certain degree of fertility. I have also detected several hybrids between P. faba var. subangu- lata, and P. virginea ; one between the arboreal P. imperforata and the terrestrial P. lugubris; two between P. lineata var. strigosa, and P. tceniata ; about a dozen between the arboreal
PARTULA.
161
P. faba and the terrestrial P. radiata; a number between P. faba and P. fusca, and many between the latter and P. navigatoria, as well as many between the latter and P. faba. I failed to detect hybrids between the Tahitian species, and found none at Huaheine. ' '
As a general proposition, apparent evidence of hybridism among land snails is so unusual in a state of nature that one is inclined to believe that well-established species very rarely hybridize. In the few species tested experimentally (such as Lang's crosses between Helix nemoralis and hortensis) the progeny are not abundant and crosses between them are almost sterile. It must be remembered, however, that the Moorean and Raiatean species mentioned as hybrid- izing by Garrett are very closely related forms, which have for the most part scarcely reached the "specific" stage of differentiation; hence it is not inherently improbable that hybrids occur.
In the case of species between which supposed hybrids are "common," I would rather explain the intermediate forms occurring on the overlapping confines of the two "pure" races as an undifferentiated remnant of the parent stock which has elsewhere become "specifically" differentiated. Pending experimental evidence to the contrary, this view seems in accordance with what seems to occur in a multi- tude of other cases, whereas hybridism on an extensive scale is certainly a very rare condition.
Variation in Partula.
Extended study of variation does not come within the plan of the present work, the purpose of this Manual being the definition of species and their systematic classification. Moreover, the materials for a study of variation — large, un- selected series of shells — are not accessible to me; my per- sonal knowledge of them is restricted to museum specimens, which as usually preserved and labelled give little idea of the assO'ciation of forms or the conditions of their existence. Some general considerations bearing upon variation may how- ever be in order.
162 PARTULA.
Most species of Partula are neither more nor less variable than the generality of snails living in exposed situations elsewhere. It is only in the Society Islands that species oc- cur having a variety of well-developed color-patterns. In this respect they resemble many other genera of arboreal snails, such as Ampliidromus, Liguus, Hemitrochus, Polymita, Drymccus etc., etc. All arboreal snails were derived from terrestrial forms ; and almost invariably, with arboreal habits they assume variegated color-patterns. In many cases the colors or patterns seem to be protective (cryptic or warning), but as often they are not so, to our eyes. The color-patterns in arboreal snails seem to be very readily modified, new sports or mutations arising, which are perpetuated, prob- ably in Mendelian ratio, in the parent colonies. This has not yet been tested experimentally in Partula; yet from the complex nature of many colonies, in which snails of several •distinct color-patterns co-exist and interbreed (being found together in the uterus of a single mother) , I have little doubt that pedigree cultures would reveal a Mendelian mixture.
Another common 'condition among tree-snails is the sim- plification or absence of pattern, by variation in the "color- factor," whereby patterns characteristic of species or phyla become in part or entirely latent in individuals or races. Cf. the Pentata-nmte snails, Drymcuus, Ampliidromus etc. Some species of Partula, such as P. liyalina, are apparently albinistic; but in at least a part of these (P. arguta) the mantle is variegated, showing through the transparent shell, which in life should vicariously show a pattern.
Probably most "species" of snails and other sedentary animals are in reality more or less complex groups, though in plain-colored forms their composite constitution is not obvious. In some of the plain, ground-living American snails, such as Omphalina, the diversity in number of teeth of the radula among different colonies points to this conclusion.
In the Society Islands, where alone the distribution of Partula has been studied, most species and races are strictly limited to small areas, a single valley, or several 'contiguous
PARTULA. 163
valleys. The topographic barriers (ridges unsuitable for Partula?) are evidently older than the races so isolated, which are the modified descendants of stocks once widely diffused. Diverse mutations soon result in racial differentiation in such isolated colonies, whether the process can be aided by di- versity of environment or not. On a small scale this is illus- trated by the colonies of Helix nemoralis in Burlington, New Jersey, all descended from a single colony planted about 50 years ago, yet now showing incipient racial traits in the several colonies scattered over the town.
Gulick, in his "Evolution, Racial and Habitudinal" p. 220 has directed attention to the fact that arboreal snails do not have the facility in migrating enjoyed by terrestrial species, and hence are more subject to local differentiation brought about by isolation.
Dr. A. G. Mayer writes: "It is probable that geographical isolation plays a most important part in the formation of new species. If two valleys be adjacent, their snails are closely related each to each, whereas the wider the separation between any two valleys, the more distant the relationship between their snails. The ridges between the valleys, being either barren or covered with vegetation unsuitable to the snails, affords barriers over which the animals must find it more or less difficult to pass. Thus the Partuke in the Tahitian valleys are isolated very much as. are the Achati- nellidas of Oahu in the Hawaiian Islands.
"In Tahiti the snails are most abundant in the valley- bottoms, where they usually occur on the under sides of the leaves of Caladium and Plantain, although in some valleys they are frequently found on Dracaena and Turmeric. Al- though more abundant in the bottom, they extend for some distance up the sides of the valley and appear to be present in most places where the plants which they affect are found. As far as the very limited observation of the writer goes, there appears to be no difference in the character of the snails in different parts of the same valley. The difference between any two adjacent valleys is, however, very marked."

Fossil Partulida:.
No fossil Partulge are known. The ancestors of this family lie buried under the South Pacific. Several Eocene and Oligoeene species have been described as Partulas, as follows :

The reference of these forms to Partula is purely fanciful. The American species is referable to a genus of Bulimulidre, Hyperaidax. Well-preserved specimens have not the char- acteristic apical sculpture of all known Partulidge. The European Eocene forms offer no character whatever separ- ating them from ''Buliminus" (Enidae). Their reference to Partula rose from the fallacious method of trying to exactly match the fossil shell with some recent species, ignoring the obvious fact that details of contour are constantly changing in the evolution of any group, and offer no features diagnostic of genera in Bulimini, Bulimuli or Partulae. The Eocene forms in question have not been shown to have the embryonic sculpture of Partula.
Classification of Partulidce.
This family contains the single genus Partula. It is quite possible that when the forms of Micronesia, Melanesia etc.
PARTULA. 165
are investigated anatomically, a further generic division may foe made. There are two rather dissimilar forms of kidney among the Polynesian species, though at present we do not know enough species anatomically to utilize this fact m taxonomy. By conchological characters nine divisions are indicated, herein called "sections." In all cases these sec- tions are geographically limited to single island-groups, or to several adjacent groups. Five of the nine sections of Partula have already been named by Dr. Hartman, who unfortunately used preoccupied names, and in most cases understood the groups in limits different from mine. He also split the typical group of Partulas into numerous sub- genera which seem to me superfluous. The subgenera here- in established are as follows.
MARQUESANA Pilsbry. Embryonic whorls coarsely pitted along the spirals ; post-embryonic whorls with very well de- veloped spiral lines ; lip .thin but often widely reflexed ; colors not bright, a subperipheral band frequently present, but no others; cuticle thin, often deciduous. Type P. gany- medes. This group includes all known Marquesan species, no. 1 to 6.
LEPTOPARTULA Pils. Shells ovate with short spire, com- posed of few (4 to 4^/2) whorls; very thin and fragile, sub- transparent, pale colored ; aperture large, ovate, toothless, lip expanded, not thickened. Type P. arguta. Huaheine and Raiatea, Society Is. Species no. 7 and 8.
PARTULA s. sir. Shell ovate, usually solid and with opaque coloring, often in bands or streaks; lip thickened within, the callus not extending to the upper insertion ; parietal wall often toothed. Society, Austral and Hervey Is., species 9- 52, and probably Samoan and Tonga Is., species 60-62.
SAMOANA Pils. The shell is very openly umbilicate, dex- tral or sinistral, with flatly reflexed lip and no teeth. Type P. canalis. Samoan Is., species 53 to 58.
THAKOMBAUA Pils. Shell rimate, long-ovate, the later whorls sculptured with coarse spiral cords. A low callous tubercle on the parietal wall far within. Type P. lirata, no.
166 PARTULA.
63. Fiji Is. This is the only group having raised spiral sculpture.
MELANESICA Pils. Shell rimate or umbilicate, ovate or pyramidal, thin, corneous, greenish-yellow or pale brown, uniform or obliquely streaked, not banded; aperture simple, the peristome expanded or reflexed. Type P. turneri. Me- lanesia, one species in Samoa. Species no. 59, 64 to 101.
A large group of species simple in form and coloring.
PALAOPARTULA Pils. Long forms with the spire straightly conic, embryonic whorls high, the later ones deeply engraved spirally, saccate below. Umbilical area very ample, deeply perforate ; aperture unusually long, tooth- less, the lip thin and very broadly reflexed. Type P. thetis. Pelew Islands. Species 102 to 104.
CAROLINELLA Pils. Perforate, rather solid, opaque and ventricose species of dull or brown coloration, aperture large and toothless. They have the appearance of ground snails. Type P. guamensis. Caroline Islands. Species 105 to 107.
MARIANELLA Pils. Shell ovate or inflated, with a small umbilicus, the lip somewhat thickened within, parietal wall plain or bearing a low nodule deep within; colors rather bright. Type P. gibba. Marianne Is. Species 109 to 111.
Geographic distribution of the Partulidce.
Snails of this family are confined to the high islands of the south and western Pacific. Not one species has ever been found on an atoll or low island. In most island groups all of the Partulae belong to a single stock, but in a few, notably the Society and Samoan groups, several phyla are repre- sented. Each of the subgenera or sections is confined to a single archipelago, or to several adjacent island- groups; and with the single exception of P. hyalina, no species is known to inhabit more than one island-group, while a great majority of the forms live on but one island. The distribution of Partulas is remarkably consistent, and lends no support to the idea that their dispersal has been due to drifting by ocean currents, or any other "accidental" means of over-sea carri-
PARTULA. 167
age. Their distribution is what would be expected were the present archipelagos remnants of a former continent, now iso- lated by subsidence. This continent, from the absence of all of the higher families of land snails on the islands remaining, I have conjectured to have been isolated since Palaeozoic times, though the final dismemberment of its various components was doubtless much later. (See Pilsbry, The Genesis of Mid-Pacific Faunas, Proc. Acad. Nat, Sci. Phila. 1900, p. 568) . Such groups as the Society Islands or Fijis may well have existed as rather large land masses as late as middle Tertiary times. Indeed, this hypothesis would seem to be an essen- tial part of any attempt to explain the distribution of land snails in most of the groups of high islands.
The most convenient grouping of species for the purposes of this monograph is by geographic range. The following divisions are used.
I. Marquesas Islands, species 1 to 6.
II. Society Islands, species 7 to 50.
III. Austral and Hervey Islands, species 9, 52.
IV. Samoan Islands, species 53 to 60.
V. Fiji Is., Kotuma and Tonga Is., species 61 to 63. VI. New Hebrides and Santa Cruz groups, species 64 to 80. VII. Solomon Islands, species 81 to 91. VIII. New Ireland, New Britain, etc., and Admiralty Is.,
species 92 to 96. IX. Louisiade Archipelago, including Trobriand and
Woodlark Is. ; New Guinea, Species 97 to 100. X. Talauer Is., species 101. XI. Pelew Islands, species 102 to 104. XII. Caroline Islands, species 105 to 108.
XIII. Marianne Islands (Guam), species 109 to 111.
XIV. Snails of other genera described as Partulse.
XV. Species of uncertain or unknown habitat, species 12, 21, 47, 48, 49, 50, 51, 60, 72, 86, 94.

11, type P. decussatula (not ^Ega Leach, 1815). — Latia Hartm., op. cit. p. 12, type P. ganymedes Pfr. (not Latia Gray, 1849).
Partulas having the embryonic shell coarsely pitted along the spirals; post-embryonic whorls with very well developed spiral striation; lip thin but often wide. Colors not bright; the cuticle thin, often deciduous; a subperipheral band fre- quently present, but no others. Type P. ganymedes.
Species of Partula are known from five of the nine high islands of the Marquesan group, the others being unknown conchologically. They are distributed as follows:
Nukuhiva : P. strigata varieties.
Huapu: P. strigata (?), P. bellula.
Hivaoa: P. inflata, P. ganymedes, P. bellula, P. decussatula.
Tahuata: P. inflata.
Fatuhiva: P. magdalinae.
The predominance of species on Hivaoa may be due to its being more fully explored. It is the largest island next to Nukuhiva. The proportion of species recorded as common to two islands is remarkable, if indeed it proves to be the fact. It seems likely that further research would greatly augment the brief list of Marquesan Partulas.
P. spadicea Reeve, reported from the Marquesas, is a Society Island form.
Key to Marquesan Partula.

1. P. INFLATA Reeve. PI. 30, figs. 1, 2, 3.
Shell openly umbilicate, globose-conic, rather thin, luster- less or nearly so, varied in color: (1) white, usually with some trace of an olive subperipheral band. (2) white, suf- fused and obliquely streaked with brown in a broad median belt, abruptly darker below the periphery; spire corneous. (3) reddish or dull chestnut brown, more or less streaked, and sometimes white below the sutures; reverse of the lip and columella white. Of the 2y2 embryonic whorls the first half whorl or more is smooth, the rest pitted along the spirals. The rest of the shell is sculptured with very distinct, close waved spiral striae. Spire is straightly conic, suture moder- ately impressed. Whorls 5%, convex, the last whorl sivollen in the peripheral region except for the space of a third or fourth of a whorl behind the lip, where it is compressed ; this gives a humped appearance to the back of the shell. Aper- ture ovate; lip broad, white, flatly reflexed, thickened with- in; columella broad, with a deep-seated fold above, visible in oblique view.
Length 23, diam. 17 mm.

Remarkable for its gibbous last whorl and broad white lip. The very thin cuticle is more or less wholly lost in most adult shells. The examples described are from the island of Taiwata (=> Tahuata) ; whether those reported from Dom- inique, the next island of the group, are identical with them in all respects I do not know.

Shell umbilicate, oblong-conic, thin, minutely, strongly, de- cussated with close growth-lines and extremely close, im- pressed, wavy, spiral lines; dead white under a very fuga- cious greenish-yellow epidermis. Spire conic, rather acute. Whorls 51/0, a little convex, the last about as long as the spire, very obsoletely angular in the middle, ornamented with one rather wide chestnut band. Columella straightened. Aper- ture oblong, obliquely truncated above ; peristome simple, thin, broadly expanded throughout. Length 23, diam. 10y2, aper- ture inside 10^x5 mm. (P/V.).

either entirely lost, or only a belt remains at and below the periphery, in adult shells. The upper edge of the subperi- pheral brown band often shows as a thin line above the sutures of the spire; but frequently a mere brown line replaces the band, and is concealed on the spire (fig. 5).
In another form of the species, the cuticle is removed in a zone below the suture. This zone may be wide or narrow; the remaining portion of the last whorl — usually half to three- fourths --is covered with greenish or dull brown cuticle. These variations seem to be characteristic of different colonies.
The beautifully developed spiral striation is characteristic of all forms. The lip is flatly reflected, thickened at the inner rim, and rather abruptly narrowed near the upper angle. The umbilical crevice is widely open.
3. P. STRIGATA Pease. PI. 30, figs. 8, 12.
The shell is openly umbilicate, acutely ovate, rather thin, dingy olive-brown, the latter part of the last whorl light cream-brownish with a few darker oblique streaks, and an orange streak in the angle behind the lip. Sculpture of fine, waved spiral lines. Embryonic shell of 2y2 whorls, coarsely pitted in spiral lines except the smoothish initial half whorl. Whorls 4%, convex, the last evenly rounded. The aperture is ovate, oblique, peristome flesh-tinted, flatly reflexed, rather narrow, thickened within except near the upper angle. Length 19, diam. 10.8, aperture 10.8 mm.

The types, one of which was figured in A. J. C. iv, are before me. The above description and figs. 8 and 12 were drawn from them. Pease gave simply Marquesas as the habitat, but Garrett istated that ' ' Pease 's shells were collected by a native missionary residing on Woapo. " This island lies south of Nukahiva. In his Marquesan catalogue of 1887 Garrett places strigata as a synonym of recta, without remark.
172 PARTULA, MARQUESAS ISLANDS.
Whether the specimens were actually taken on Huapu ("Woapo") or not remains uncertain.
Compared with the type lot of Pease's P. recta, P. strigata is thinner, darker colored, dull 'brownish instead of pale green, with a narrower flesh-tinted peristome. The two lots seem to he specifically distinct, until studied in connection with a large series from Nukahiva, subsequently obtained, which seem to be partially intermediate.
3a. P. STRIGATA OBESIOR Pils. PI. 30, figs. 11, 14, 15, 16.
A lot of 27 examples from Nukahiva consists of shells which are generally more globose than either recta or strigata, thin, variable in color as follows :
a. White, denuded of cuticle (fig. 14).
&. White, covered with a very thin straw, cream or brown tinted cuticle, the spire often corneous (fig. 15).
c. Rusty brown, having a whitish belt below the suture (fig. 16).
d. Dark brown (fig. 11).
In nearly all of this lot the lip is thin and narrow, as in strigata. Specimens measure:
Length 21,. diam. 12.8, aperture 11.8 mm., whorls 5.
Length 20.8 diam. 12, aperture 11 mm., whorls 5.
Length 19, diam. 11.8, aperture 11 nun., whorls 5.
Length 18.5, diam. 10.5, aperture 10 mm., whorls 4%.
Length 17, diam. 10.5, aperture 10 mm., whorls 4%.
A few examples among these shells are typical recta. Probably a collector who would keep his shells from different colonies separate would find that there are several races on Nukahiva.
3&. P. STRIGATA RECTA Pease. PI. 30, figs. 9, 10.
The shell is openly umbilicate, acutely long-ovate, solid, the typical form -white under a very thin, very pale green cuticle, which is often deciduous on the last half whorl. The spire is straightly conic, whorls 5*4 convex, the last one equably curved from suture to base. The initial half whorl is smooth,

next two whorls of the embryonic shell are rather coarsely pitted in spiral lines, following whorls marked with fine growth-lines and very fine spiral strise, most distinct at the base.

Surface somewhat shining, with sculpture of fine spiral striae which are crowded and wavy on the base, but separated by spaces much wider than the impressed lines on the upper part of the last whorl. 2^ embryonic whorls (fig. 19) have the coarse pitting of other Marquesan species. Spire short, straightly conic ; whorls 4^, moderately convex, the last inflated, almost equably convex, 'but the base is es- pecially so.

The type specimen (no 4264 Carnegie Mus.) is not completely mature, wanting the narrow callous inner rim of the peristome, but there are several fully adult shells with younger ones in the collection of the Academy, taken by C.

A thin, inflated species, yellowish-corneous slightly brown tinted towards the summit, with a pale border below the suture denuded of cuticle, and a narrow very faint brown band just below the periphery. This band is sometimes very inconspicuous. Old shells lose much of the cuticle, becom- ing whitish and opaque. The aperture is ample.

This very delicate snail is related to P. decussatula Pfr., but it is very much more inflated, shorter, with a narrower um- bilicus. Of the four examples originally composing the type lot, one has been broken; the example figured by Hartrnan is also damaged by a hole in front (not shown in my figure of this specimen). Perhaps none of the specimens is quite fully mature, but it is evidently a very thin shell at any stage of growth. Figured from cotypes, no. 4263 Carnegie Museum.
II. SPECIES OF THE SOCIETY ISLANDS.
The Society Islands are wonderfully rich in Partulas. Both species and individuals are developed in profusion, and differentiation of form and color has been carried further than in any other island group, though there has been no great structural divergence. Probably all of the Society species are referable to two stocks, herein regarded as "sec- tions. ' ' These sections may be defined thus : I. Shell ovate, with short spire, composed of 4 to 4=y2 whorls, very thin, fragile and subtranslucent ; color pale and

simple; aperture ample, peristome expanded, not thick- ened. Section Leptopartula, species 7 and 8. II. Shell composed of more than 4.y2 whorls, usually solid, with opaque coloring, but sometimes white ; lip thickened within. Section Partula, species 9 to 50. Up to this time we owe our knowledge of the distribution and variation of Society Island Partulae to Andrew Garrett, whose residence at Tahiti gave him unusual facilities for their study. In the following account I have quoted largely from his writings and except in a few cases, have accepted his esti- mate of the rank of the several species and races. In a case like this, where races in all degrees of differentiation abound, the rank to be assigned to any given race is, in the last re- sort, a matter of opinion. The criterion of intergradation is often difficult of application, as where the racial divergence is expressed chiefly in slightly different tendencies of varia- tion. In Raiatea and Tahaa especially, there seems to be a good deal of intergradation between the races and so-called species.

It occurs much more rarely in a neighbor- ing valley south of its specific center. Mr. Pease's habitat 'Tahiti,' as given in his list of Polynesian land shells, is decidedly wrong." (Garrett}.

Though referred by Pease to the genus Bulimus, it is, never- theless, a true Partula. "The animal, which is viviparous, has very long, slender, ocular tentacles, long lance-pointed foot, and that portion of the animal occupying the whorls of the translucent shells is beautifully maculated with black and white spots on grayish yellow ground. The shell, which is very uniform in all its specific characters, may be readily distinguished by its very thin pellucid texture, ovate form, abbreviated spire, turgid body-whorl, uniform pale yellow- ish horn-color, thin, slightly expanded lip and large simple aperture. ' ' ( Garrett) .

The shell is shortly, openly rimate, not perforate, short, obliquely ovate, extremely thin, fragile, corneous, faintly tinted with pale brown, slightly transparent. The surface is glossy, marked with growth-lines and minute, close, spiral striae. Spire very short, conic; suture marked with a fine white line.

This delicate shell is larger and more opaque than P. arguta, and differs in the non-perforating umbilical fissure. Garrett remarks that "Like P. clara and P. annectens, it appears to be gradually becoming extinct. ' '

The typical group of Partula is restricted to the Society and Hervey Islands. Each island has its minor type of shell, except Moorea and Tahaa, which have Tahiti an and Raiatean types respectively ; 'but the entire series is so closely interrelated that the named subgenerie divisions proposed by Dr. Hartman cannot be sustained.
A small group of white, translucent species includes
No. 9, P. hyalina Brod. Tahiti, Hervey and Austral Islands.
No. 16, P. clara Pse. Tahiti.
No. 17, P. attenuata Pse. Tahiti and Raiatea.
No. 44, P. annectens Pse. Huaheine.
These forms may have some exceptional means of distribu- tion, or they may be conservative stocks, which have altered little since the original radiation over the mountain ranges which are now islands. They approach the simply colored southwestern forms of Partula, such as those of the Solomon Islands, in appearance, and seem to be little-changed mem- bers of an old stock.
The species are here treated in geographic order, as follows :
1. Tahiti, species 9 to 17.
2. Moorea, species 18 to 21.
3. Raiatea and Tahaa, species 22 to 41, 8.
4. Huaheine, species 42 to 44, 7.
5. Borabora, species 45.
6. Species of uncertain habitat, species 46 to 50.
1. Partulce of Tahiti.
"On Tahiti, the largest island in the group, we find eight species only, six of which are endemic. One (P. clara}, which has a limited range, appears to be gradually becoming extinct. Four species (P. filosa, nodosa, producta and stolida) are each restricted to a single valley. All the above species are well-defined, and exhibit but little variation. On the contrary, P. otaheitana, which has its centre of distribution
180 PARTULA, TAHITI.
in Fa.utaua valley, has spread all round the island, and is sub- ject to so much variation that no less than fourteen species have 'been proposed for the different forms. Two species (P. hyalina and attenuata) are common to other islands; the former is found in the Austral and on one of the Cook's group ; the latter occurs on Raiatea, but does not inhabit the two intermediate islands. It is a .noteworthy fact that, not- withstanding both species have spread nearly all round Tahiti, yet they have not developed a single varietal feature, but, on the contrary, are remarkably uniform in all their specific characters.
"Here we have three species ranging round the island, and all subject to the same conditions of life, yet two have not shown the slightest tendency to depart from the typical forms, and the other, which is very variable in its metropolis, has developed many local varieties. The above facts, which are common to other species, seem to suggest that physical con- ditions are not the primary cause of variations, but that it is the operation of some unknown law." (Garrett).
Numerous forms of Tahiti and Moorea are sinistral. The species of all the other islands are invariably dextral. Sin- istral Partulae also occur in the Samoan group.

Quite distinct 'by its milk-white color, and the very oblique aperture, contracted in adult shells by a strong inner rib of the lip. It might form a separate subgenus.
The distribution of this snail on several widely separated groups is remarkable. Such distribution is unparalleled by any land snail of its size in Polynesia. I have not seen specimens from Mangaia or Rurutu, but those collected by Voy at Rarotonga seem indistinguishable from Tahitian ex- amples. It seems possible that it has been distributed by hu- man agency, since it is not likely that a snail of this size could be carried far over sea by hurricanes, as the minute forms (Tornatellina, Pupidce etc.) no doubt have been. Still an- other hypothesis : P. hyalina may be an ancient and conserva- tive stock, which has survived from the time when these mountain islands formed the sierras of a larger land mass.

The descriptions of Reeve and of Pfeiffer are given above. The type specimen is represented by fig. 21, copied from Reeve who described the species in advance of Pfeiffer. The figure measures about 24 mm. long. The last whorl is dark chestnut colored.
Three specimens received as P. compressa from Mr. Cuming in 1862 are before me, two being figured, pi. 41, figs. 19, 20. The shell is glossy, with very fine and rather weak spiral striation. The color in one shell is white under a yellow cuticle, closely streaked with olive-yellow, the streaks form- ing an ill-defined median belt. The other specimens are very finely, closely but irregularly streaked with brown, on a yellow ground on the last whorl, giving a rather bright red- dish or yellowish brown appearance, while the spire is dull or liver brown, the apex dull purplish-brown. The last whorl is very conspicuously compressed laterally, flat there in the last half-whorl. The aperture is diagonal, the base thrown out from the middle, in the type figure and in the yellow shell before me (fig. 19), but in a smaller shell it is normal in shape. The lip is reflexed, heavily thickened within. The interior is white.

These specimens agree perfectly with one received from Andrew Garrett as P. stolida, and which he figured in Journ. A. N. S. Phila. ix, p. 70, pi. 3, fig. 58. I have drawn this

shell somewhat enlarged on pi. 25, fig. 7. It has some re- semblance to P. a/finis, but the last whorl is far more com- pressed laterally than in affinis. The spire is reddish-brown, becoming darker towards the apex, which is blackish-purple. The last whorl is olivaceous-chestnut, closely streaked with yellow. The last half of the last whorl is strongly com- pressed at the side, with a very convex, "saccate" base. The umbilical crease is rather ample. The rather narrowly re- flexed lip is fleshy-tinted, thin-edged, having a strong in- ternal thickening. No parietal tooth. Sculpture consists of very fine and close spiral striae crossing the growth- wrinkles, and continuing to the lip. This shell measures, length 19, diam. 11, length of aperture 10 mm. G-arrett writes: "I took a few examples of this ground species about two miles up Papenoo valley, on the northeast coast of Tahiti. They were all found lurking among the roots of ferns."
The identity of the original P. stolida of Pease is doubt- ful. There is little in the description to exclude it from P. compressa, yet the statement that it is "dentate" prob- ably indicates that what Pease originally had was a form closer to P. affiuis (no.

"This species is fluviatile and was discovered during the same voyage as the preceding [Captain Cook's], in the brooks of the island Otahiti. The shell is sinistral, oblong, oval, very thick, not more than 10 or 11 lines in length by about 6 in diameter. It is composed of 5 whorls, united exteriorly, and as much swollen as those of the austral Bulimus, but coiled in a direction contrary to that of most shells; that is to say, the right side of its animal is towards the left. The spire is conic and terminates in a pointed summit. The sutures resemble those of the preceding species [P. faba]. The 'aperture is semi-oval, oblique, rounded at the base, only a third longer than wide, and shorter (by a line than half the shell. Outer lip arcuate, much reflexed and recurved to

The inner [parietal] lip is very thin and furnished with a tooth in the middle, only found in old shells, the young having an in- conspicuous callus in its place. The •columella is simple, out- wardly covering an umbilicus resembling that of Bulimus australis. The whole shell is brown outside, or the color of roasted coffee; the lips are whitish and the cavity sooty. It is not common. ' ' (Brug.}.

Bruguiere's account is given above, since it seems to indi- cate a darker, more elongate shell than that generally ac- cepted as typical otaheitana.
"The metropolis of the typical otaheitana is about two miles up Pautaua valley, on the northwest part of Tahiti, where it is very abundant on the trunks and foliage of trees and bushes. The above-mentioned valley being close to the principal harbor which was frequented by the early naviga- tors, it was undoubtedly where Bruguiere's type was ob- tained.
' ' The Fautaua shells, which are very variable in size, shape, and color, are never ornamented by spiral bands, and about one-third of the specimens are sinistral. The parietal tooth is nearly always present in the adults, and the peristome, though usually white, is frequently pinky flesh-color. The prevailing colors are straw-yellow, reddish fulvous, light 'chestnut, frequently with the spire more or less tinted with reddish and often with longitudinal strigations. The spire is more or less produced, and the aperture varies some in size and shape.
"The shape of the shell varies from abbreviate-ovate to elongate-ovate, as the following measurements will show: Length 21, diana. 10 mm. Dextral specimen. Length 16, diam. 10 mm. Dextral specimen.
186 PARTULA, TAHITI.
Length 20, diam. 10 mm. Sinistral specimen. Length 16, diam. 9mm. Sinistral specimen."
The following form has been referred to otakeitana as a synonym by Garrett and Hartman. "Bulimus isabellinus Pfr. Shell subperforate, oblong-conic, solid, striatulate, isa- belline. Spire conic, rather acute. Whorls 5, a little con- vex, the upper sculptured with impressed, very delicate spiral lines, the last, a little shorter than the spire, base rounded in front. Columella white, plicate-gibbous. Aperture ob- long-oval, narrowed by a dentiform callus deep within on the belly of the penultimate whorl. Peristome callous, white, broadly expanded, a little reflexed, the columellar margin dilated, sinuous-reflexed. Length 22, diam. 10, aperture in- side 9 mm. long, 4!/o wide. Habitat unknown, Mus. Cuming. ' ' (Pfr.) Reeve's figure is copied, pi. 26, fig. 16.
P. Iccvigata Pfr. is doubtless a Society Island shell, prob- ably a form of P. otaheitana. The description follows:
P. Iccvigata, Pf eiff er. — ' ' Shell deeply rimate, ovate-conic, solid, smooth, (slightly striatulate under the lens), glossy, buff. Spire conic, rather obtuse; suture moderate.

"In a valley about two miles west of Fautaua, there exists in abund- ance the variety ( ? ) lignaria, Pease, which, though described as dextral, is nevertheless very frequently sinistral.

wore strigated, as well as exhibiting one to three transverse reddish chestnut bands. The lip is always white, and the parietal tooth is very seldom absent. The inosculation with otakeitana is so complete that it cannot be even separated as a well-marked variety." It was thus described: Partula lignaria Pease in Proc. Zool. Soc. 1864, p. 671. " P. t. ovata, solidiusculai dextrorsa, anguste umbilicata, sub lente minu- tissime transversim striata, irregulariter longitudinaliter striata; anfr. 5, plano-convexis, sutura impressa; apertura rotundato-ovata, edentata, labro rotundatim incrassato ; cas- taneo-fusco irregulariter longitudinaliter strigata, interdum omnino rufo-fusca. Long. 18, diam. 10 mill."
"Var. &. Fascia unica nigro-fusca cingulata, seu omnino fiavide fusca. "
G-arrett's note on this imperfectly differentiated race is given above. The figures are from shells collected by him, showing several color-patterns. In certain examples a more or less conspicuous nodule appears on the face of the colu- mella near its insertion, fig. 4, much as in P. auriculata and nodosa.
Dr. Mayer found lignaria streaked without spiral bands, and also with one dark peripheral band in Tipasrui valley. All were dextral. In a few there is an additional subsutural band.
In Hamuta and Pirae Valleys, a form with sutural, peri- pheral and umbilical bands was found, constituting 3 to 4 per cent of the Partulcc caken. It occurred with streaked Lignaria. In Pirse, all are sinistral; in Hamuta (between Piras and Tipoerui) both dextral and sinistral individuals were found.

"Var. encircled with three dark reddish brown bands, on middle of last whorl, at the umbilicus, and just beneath the suture.
"Observations: The above species is allied to P. otaheitana. It is, however, smaller and less elongate." (Pease).
Garrett writes: "Pease's affinis, which cannot be separated from some of the small abbreviated forms of otaheitana, oc- curs in greater or less abundance in all the valleys from Haona as far as the southeast end of Taiarapu peninsula, and round the opposite coast as far as Papieri on the south- west of Tahiti proper. In Papinoo I discovered a large colony of affinis, many of which had the pinky flesh-colored lip and sinistral form of otaheitana. Far up in the same valley, though common, none but dextral forms were found, and out of thousands taken in the other valleys, not one sinistral ex- ample occurred to my notice.
Three examples of affinis, received from Pease, and rep- resenting the three color-forms mentioned by him, are fig- ured, pi. 25, figs. 5, 6, 9. All the examples of this lot have the parietal wall dentate. The sculpture of spiral lines is very fine and close, but on the last whorl it is more or less obsolete, especially so in the middle of each whorl.
In a lot of five examples received from Garrett, one has a small parietal tooth, the others none. All are obscurely streaked with chestnut on a yellow ground, the spire brown. The sculpture of the latter part of the last whorl below the suture, of one of this lot, is drawn in pi. 25, fig. 8. In some other individuals, the spiral lines are subobsolete, as in typical affinis.

The var. dubia was not defined by Pease, but only mentioned as a form of varia, in P. Z. S. 1864, p. 675. Its first published definition was in Garrett's note, quoted above.

"To the eastward between Fautana and Papinoo valley, a distance of about eight miles, there are three valleys, all in- habited by Pfeiffer 's amabilis, a sinistral form which has not a single feature to distinguish it from some of the large turreted Fautaua shells. In the first valley, Pfeiffer's species, though not abundant, were very fine specimens. The next valley, known as Pirai, (the metropolis of the small dextral P. filosa, which occupies the lower part of the valley), is, in the upper part, which trends towards the headquarters of otaheitana, inhabited by the sinistral amabilis. A few im- mature examples were found which were 'banded like lignaria. The only dextral Partulce taken in the two valleys were filosa,, attenuata and hyalina.
"In the next valley, called Haona, I found the dextral P. affinis abundant, and took a few of amabilis.

Fig. 4 is a copy of Reeve's. The examples before me are the form sent out as turricula by Pease. They are all sinis- tral, elongate, glossy, varying from chestnut-tinted yellow to pale yellow with light green streaks on the last two whorls, those preceding rose-tinted, the shade deepening to the apex. The lip is white in the paler shells, rose-tinted in the darker. Measurements vary from length 22, diam. 12.1, aperture 10.9 mm., to 19, 11, 9.8 mm. just three-fourths of the adult shells seen have a parietal tooth. Garrett writes: "Reeve's rubes- cens is abundant in Papinoo, and occurs sparingly in all the valleys as far as the southeast end of the island. Like ama- bilis it cannot be separated from the sinistral turreted ota- heitana, inhabiting Fautaua. It is always sinistral, never banded, and, though usually of a reddish tint, is frequently straw-yellow or fulvous, with or without a reddish or pinky apex. The lip is white or pinky flesh-color. Though de- scribed as edentate, some have a small parietal tooth. Reeve gave no locality, and Pfeiffer erroneously cites the Marquesas as its habitat."

valleys and lowland forests for a distance of ten or twelve miles. In the valley which is the limit of the range of the dextral affinis I took several specimens of the sinistral sinis- trorsa. The latter is invariably reversed, dentate or eden- tate, fulvous with three more or less diffused reddish chest- nut bands. Reeve figures the same shell on Plate 3, fig. 13a, as otaheitana. Bandless varieties are frequent, and vary from straw-yellow to fulvous or light chestnut, frequently strigated and the lip white. The 'latter varieties differ none from the true otaheitana of Fautaua.
" It is worthy of remark that in that part of the district of Papieri, occupied by sinistrorsa, is also the headquarters of the terrestrial P. producta, a dextral species, which is always edentate, and exhibits the fasciation of the former.
"After passing to the westward of the range of the typical sinistrorsa, which presents the same features for a distance of ten or twelve miles, it suddenly exhibits a tendency to a change in its becoming more stunted, more solid, always den- tated, and the bands, one to three, are sharply defined on a pale ground. It is the sinistralis of Pease, MS., and occupies two valleys.
"In the next large valley, called Faahuaite, on the south- west coast, we find Pease's crassa (MS.), which is also a sin- istral shell, always dentated, solid, more tightly coiled than sinistrorsa, and the body- whorl is more flattened. It is rarely marked by a single narrow submedian chestnut band. In the same valley, but more inland, occurs a smaller form, which is, I suppose, the P. brevicula, Pse., MS. [see pi. 26, f. 12, speci- men from Dr. Hartman].
' ' The following valley, named Punaavia, is the metropolis of the beautiful P. nodosa, which also exhibits three bands. Far above the restricted range of the latter, where the valley turns towards the head of Fautaua, the home of the typical otaheitana, I took a few examples of a Partula, similar to, but larger than crassa. The next valley is the habitat of lignaria. ' ' ( Garrett) .

In my copy of Pfeiffer's figure (pi. 27, fig. 13) the small parietal tooth was omitted by oversight. It is very indis- tinctly drawn in the original figure, and should resemble that of fig. 9 of the same plate.
P. stenostoma was not identified by Mr. Garrett. The positions of the bands eause me to think it related to affinis Pse., and dubia Garr., but it differs from these and other forms of P. otaheitana by the narrow shape of the aperture. Dr. Hartman has referred stenostoma, to P. vexillum Pse. ; and it has a certain resemblance to the Raiatean P. planila- brum and P. vittata.

This terrestrial form was found by Garrett to be invariably dextral. It is not so glossy as P. otaheitana sinistrorsa Pse., but otherwise there is not much difference. P. producta how- ever has somewhat diverse variations; the dark bands be- come confluent in some individuals by darkening of the ground color, leaving the last whorl chestnut with (usually) a pale sutural band and umbilical patch. Garrett also re- cords a mutation uniform pale fulvous or tawny with a darker apex. Description and figs. 1, 2, 3 from examples received from Pease.

Tahiti : ' ' This beautiful arboreal species is restricted to a limited area about two miles up Punaavia valley on the west coast of Tahiti. I first discovered the location in 1861, and gathered about three hundred examples. On a subsequent visit, nine years later, I secured over eight hundred speci- mens. It is entirely confined to the south side of the stream which flows through the valley, and circumscribed in a nar- row area about three-fourths of a mile in length." (Garrett) .

P. nodosa stands near P. suturalis of Moorea, which doubt- less arose from the same ancestral stock. In Tahiti it has no little resemblance to certain forms of P. lignaria, especially those with many streaks and a single dark belt, many of which show a more or less developed nodule on the columella, such as is characteristic of P. nodosa.
The typical P. nodosa, pi. 25, figs. 12, 13, was the dark reddish-brown or chestnut-brown shell, with a wide cream- white band below the suture on the last one or two whorls.
PARTULA, TAHITI. 195
There is usually more or less pale streaking of the dark ground on the last whorl; the reverse of the lip and the border of the umbilicus are also pale. Several examples seen, one of them received from Dr. Pfeiffer. All are dextral. Judging 'by the lots before me, this form occurs in the same colonies with the following color phases.
Color-form TRILINEATA Pease. PI. 25, figs. 14, 15. "Cream color or yellowish horn-color, the spire usually reddish-brown, last whorl striped irregularly with brown, and encircled by three dark reddish-'brown lines or 'bands; suture margined with white "(Pse). In the typical lot of trilineata received from Pease the spire is fleshy brown in two examples (typical -coloration) ; clear corneous in two; and the other two have some whitish and faint 'brown markings on a fleshy- corneous ground. Four of the shells are 3-banded, like fig. 14, 15, one has only a wide chestnut 'belt, and is conspicuously streaked with brown, and the sixth is a typical nodosa in color.
A lot from Grarrett consists of ( 1 ) ordinary dark P. nodosa ; (2) one sinistral shell (fig. 16) with normal trilineata color- pattern. Garrett states "about one in two hundred is sinis- tral ") ; and (3) pale shells with the spire corneous, last I1/-* whorls cream-colored with a profusion of corneous and cor- neous-brown streaks which do not reach to the suture; aper- ture typical (pi. 25, fig. 17, color- form pallidior).

' ' The shell is blunt in shape and the spire is short ; the lip is quite thick, and is usually provided with a well-developed tooth upon the columellar side, and there is also a tooth upon the wall of the aperture. The surface of the shell is smooth and slightly polished, and there are no deep longitudinal fur- rows. About 57 per cent of these snails are well represented by fig. 18. The ground color is a light horny-yellow streaked longitudinally with darker brown, in addition to which there are two dark-brown whorl-stripes and a white whorl-stripe adjacent to the suture of the spire. In about 43 per cent the dark-brown whorl stripes are either absent or veiy faint,
196 PARTULA, TAHITI.
and the ground color of the shell varies from light horny- yellow to rich 'brown. A snail of this type is fairly well rep- resented in fig. 19, a dark-brown individual being drawn. Ninety-seven per cent of the adult snails of type 18 and 91 per cent of type 19 -are sinistral ; while of the young, 100 per cent from type 18 and 90 per cent from type 19 are sinistral. In the case of the snails of type 19, twenty-six sinistral adults gave forty-six sinistral and one dextral young; while two dex- tral adults gave four dextral and no sinistral young. Among the snails of type 18, only one of the dextral adults con- tained young and this one gave a single sinistral offspring. Twenty- six whorl-striped adults of the type of fig. 18 gave forty-two young, of which 76 per cent display whorl-stripes, while 24 per cent are plain colored. On the other hand, twenty-eight adults of type 19, which are either unstriped or with very faint whorl-stripes, gave forty-one young of which 61.5 per cent are marked with whorl-stripes and 38.5 per cent are plain colored. It is very evident that the striped and unstriped forms intergrade.
"Of the one hundred adults found in the valley, 94 per cent are sinistral, while of the eighty-eight young taken from them, 94.5 per cent are sinistral. This condition appears, therefore, to be stable from one generation to another." (Mayer}.

P. filosa is quite distinct from other Tahitian snails, but is very closely related to the Moorean P. nucleola Pse. It is a small, ovate, solid and compactly coiled shell, dull or with but little gloss, and either reddish-brown with darker pur- plish summit, or dull yellow with the summit roseate; in either case 'being irregularly marked with many backwardly sloping longitudinal whitish lines. Under the lens these lines appear ragged, and are seen to be due to the loss of cuticle along some of the lines of growth. All the post-embryonic whorls have this peculiarity. The spiral striation is well developed throughout. All of the thirty examples seen have a parietal tooth, but in some it is quite small. The peristome is white, moderately expanded but strongly thickened within. There is often the low indication of a tubercle on the colu- mella. No banded or sinistral examples have been found.

This leaf-dweller is said by Garrett to be rare and in his opinion approaching extinction. It has the figure of P. annectens of Huaheine, but is much less delicate. P. attenuata of Raiatea and Tahiti, is an allied species of much more slender contour.
Specimens from Pease and Garrett before one are either nearly uniform in tint, or streaked obliquely with chestnut. Pease in his original account has described a livar., encircled with a single line, or two or three." Garrett describes it as "corneous, sometimes with darker stripes, and more rarely with one or two transverse chestnut bands. ' ' In being varie- gated, P. clara is -clearly less modified from the ancestral stock than P. attenuata and annectens.

This snail is closely related to P. annectens of Huaheine, having in common with that the color, texture and sculpture, and especially the peculiar shape of the last whorl, which is compressed below the middle, then swollen around the umbili- cal region in both species. It differs from annectens by its
200 PARTULA, MOOREA.
more slender shape, heavier substance, and wider lip, which is calloused within. P. clara also is an allied species of broader contour, but with an aperture much like that of attenuata.
In a lot or three specimens sent many years ago by Pease, the suture has a grayish margin ; but in all other shells seen, the margin is white, by loss of the cuticle, or by its becoming permeated with air. Normally the lip-edge and parietal callus are thin, but in one very old shell before me, both are considerably thickened.
Pease described this species twice, evidently from the same examples. He seems to have forgotten the description of 1864. It is an error other prolific authors have committed.
"When we take into consideration its peculiar habit of concealment in the tops of trees, and its range restricted to the more elevated portions of the valleys, so contrary to the habits of other species, it is really remarkable to find it in- habiting two remote islands, especially as all the other species have a very limited range. It does not occur at Tahaa, which is only four miles from Raiatea, and enclosed in the same en- circling reef. It is no less singular to note its absence from Huaheine and Moorea, though at the former island we find the closely allied P. annectens." (Garrett).
2. Moorean Partula.
Four species and numerous subspecies are peculiar to Moorea, which is separated from Tahiti by a channel only eight miles wide. All show clear traces of a common ancestry with Tahitian forms, though since the separation of the islands there has been specific divergence. The affinities of the snails are as follows :

P. nworeana "may be characterized by its elongate-ovate form, rather thin texture, constant parietal tooth, planulate- conical spire, which equals half the length of the shell, pale luteous color, with darker apex. It is alivays sinistral, and the white expanded lip is rather thin and moderately incras- sated. A variety with three narrow pale brown revolving bands is not infrequent.
"It is closely related to some of the sinistral forms of varieties of P. otaheitana, particularly with Pease's P. crassa, which, though of the same shape, is more solid, rougher, and the fine crowded spiral incised lines which extend over the whole surface of the former are nearly obsolete on the latter."

The original figures of this species are copied, pi. 27, figs. 10, 11. It was described from the Curning collection, the habitat being unknown. Dr. Hartman seems to have first re- cognized it in the common Moorean shell under considera- tion. Garrett subsequently (1884) discussed the species at great length.
Figures 5, 6, 8 of plate 28 represent the typical form of the species. The shell is rather solid when adult, compact in shape. The lip is snow-white, thickened within, columella vertical, swollen or inflated just below the insertion.

sometimes nearly white, and the stripes are brown-corneous or even, unequal and unevenly spaced. The sculpture consists of spiral incised striae which are rather widely spaced, and typically are distinct on the last whorl.
This type of shell is further modified by the development of spiral bands; sometimes only one, at the periphery, the base of the shell often chestnut-colored, and again two bands, one above, the other below the periphery (pi. 28, fig. 8; pi. 27, fig. 6). Specimens with oblique streaks only, with one and with two bands, occur together in Garrett 's sendings, and apparently are mingled in the same colonies. The spiral striation is usually subobsolete on the upper part of the last whorl in these shells, which are what Pease named in MS. and Smith described as P. alternata. The preceding forms are what Garrett alludes to as found in Oahumi valley. Com- paring this race with vexillum, he writes: "The Oahumi shells are usually a trifle smaller, not so frequently dentated, and are much more conspicuously strigated than the Vaianai shells. The spiral bands, of which there are one or two, sel- dom three, on the body- whorl, are very frequently interrupted, which, with the conspicuous strigations, gives the shell a some- what tessellated appearance. All the color-varieties alluded to in my remarks on the Vaianai shells are also found in Oahumi, but the uniform dark-colored ones are more fre- quent, besides one of a uniform white color, not decorticated, of which I took three examples.
"So far as I can ascertain, there has been no figure pub- lished of Pfeiffer's strigosa. He gives the Admiralty Islands as its habitat. There are no species of the type he describes found in the western Pacific. It is undoubtedly a Society Islands species, and I fully agree with Dr. Hartman in re- ferring it to the shells under consideration. ' '
Further Oahumi color-forms are represented in pi. 28, figs. 1, 2, 3, 4, the lot from Garrett. They are chestnut with light streaks and a white suture, the spire flesh-colored (fig. 3), the same with a pale girdle (fig. 2), or line (fig. 1), at the peri- phery, or there may be two white zones, one below the suture, the other in the middle of the basal slope (fig. 4).
204 PARTULA, MOOREA.
P. strigosa Pfr. is p rob-ably, as Garrett and Hartman have held, a form of suturalis. It w:as described as follows : ' ' Shell perforate, oblong-conic, rather solid, very obsoletely decus- sate, subopaque ; whitish, ornamented with irregular fulvous and rufous streaks. Spire conic, the apex acute. Whorls 5, nearly flat, the last slightly shorter than the spire, somewhat tapering at the base, rounded. Columella somewhat twisted above, subnodose at base. Aperture slightly oblique, trun- cate-oval, generally contracted by a nodiform parietal callus. Peristome white, callous, subequally spreading throughout. Length 17 to 18, diam. 9 mm., aperture with peristome 8^2 x 6% mm., inside 3% mm. wide. Admiralty Is." (P. strigosa PFR., P. Z. S. 1856, p. 384).
. P. SUTURALIS VEXILLUM Pease. PI. 27, fig. 9 ; pi. 28, figs. 9-12.
The shell is typically dextral, more lengthened than the preceding, less compact, and somewhat thinner. On a corn- eous-buff ground it is obliquely streaked with opaque buff on the last whorl, and begirt with two chestnut bands, the upper one ascending on the penult, whorl. Parietal tooth well-developed. Spiral striation wanting or extremely weak on the last whorl. Sutural white line inconspicuous or even wanting. Length 21, diam. ll1/^, length of aperture 11 mm. Description and fig. 9 are from one of Pease's original lot. Other shells are somewhat smaller, length 18 mm., and the oblique streaks may be less distinct,
Many examples were collected by Andrew Garrett, who found it variable. Some shells are dark chestnut with a white sutural line (fig. 10) ; others are like Pease's original lot, or have a third band, around the umbilicus (fig. 11) ; while some shells are finely streaked brown and buff, without any bands (fig. 12) . Garrett writes as follows : "This beau- tiful arboreal species is found in great profusion in Vaianai valley, on the southeast coast of Moorea, where it occurs in company with P. mooreana and P. elongata. It also exists in considerable numbers in a small valley about two miles to the westward, associated with P. taniata and elongata.
PARTULA, MOOREA. 205
' ' I first discovered this species in 1861, and obtained several hundred specimens, all collected on the eastern side of the stream that flows through the valley of Vaianai. They were all dextral, and were so described by Pease, under the name of vexillum. On a second visit, in 1875, I took over 2000 ex- amples, all gathered on the tvestern side of the stream, and was surprised to find many sinistral forms among them [pi. 28, fig. 9]. At the same time I found about a dozen specimens, all sinistral, in a large semicircular valley on the opposite side of the island. They were probably stragglers from Vaianai.
"It is noteworthy that no reversed Partulce were found in any other part of the island except on the western side of the stream in Vaianai, and the above-mentioned stragglers taken on the opposite coast. The same side of the stream is also the home of the sinistral P. mooreana."

Tlie typical form is tawny brown with two widely separ- ated white bands as shown in figures 15, 16 of pi. 28. There are also often some pale oblique streaks. The shape, as (jarrett writes, "varies from abbreviate-ovate to elongate- ovate, more or less solid, scarcely shining, smooth or wrin- kled with incremental strige, and the spiral incised lines are very fine, and crowded on all the whorls. The spire is more or less produced half the length of the shell, sometimes shorter or a trifle longer. The last whorl is frequently com- pressed in the back and right side, which gives it a faintly biangular appearance. The peristome is more or less ex- panded, sometimes considerably so, moderately thick, slant- ing and labiated within. Columellar lip more or less tor- tuous, abruptly receding above, which gives it a nodulous ap- pearance. About one in a hundred exhibits the parietal tooth. The color is also variable : white, straw-yellow, lemon- yellow, light orange, corneous, fulvous, various shades of brown, sometimes with darker stri gallons, and frequently spirally banded. The most common style of fasciation con- sists of from one to four narrow, more or less broken, fulvous or fulvous-brown bands on the body-whorl. Fulvous-brown examples, with two or three pale bands, are not so common. The last appears to be Morch's type, which he incorrectly as- signs to the Viti Islands."
"The metropolis of this truly protean species is in a very large semicircular valley on the north coast of Moorea, where it occurs in prodigious numbers on the foliage of bushes. In the western part oi the same valley, where it exhibits less variation, it gradually intergrades with the form which has been distributed under the name of nucleola Pease, which has its headquarters in a small, but isolated, valley about two miles west of Opunohu.
PARTULA, MOOREA. 207
' ' On the -southwest part of the island we find tceniata toler- ably abundant in three valleys, and, like the shells in the western part of Opunohu, it is subject to much less variation than obtains in the eastern part of the same valley. The shells from the southwest coast were described by Pease un- der the name of P. simulans [pi. 29, figs. 8, 12, 13].
"In the third or more eastern valley, where they come in contact with P. elongata and lineata, hybrids between the former and tceniata are so numerous that, any one collecting in that valley only would, without hesitation, pronounce them one and the same species.
"From this point to a distance of several miles, the valleys are inhabited by lineata, mooreana, elongata and lineata, var. stngosa, only. But after passing Oahumi, the home of the latter variety, we again find tceniata, but nearly as variable as the eastern Opunohu shells, and mixed with the form known as striolata, Pse., with which it intergrades. Here I found several unmistakable hybrids between strigosa and tceniata. All the valleys between this latter location and the one near- est to Opunohu are inhabited by the typical form striolata, which scarcely differs from nucleola, except in being smoother and more variegated with stripes. In a large valley adja- cent to Opunohu, we find these shells by thousands; they differ in being beautifully striped like stngosa. Here, again, it insensibly graduates into the typical tceniata. Whether the inosculation takes place through hybrids or not is a difficult question to decide. In looking over a large collection from the eastern part of Opunohu, I find some of the small forms are not dissimilar to the typical striolata, which has suggested the propriety of following Dr. Hartman in consolidating the three forms." (Garrett).

An example of P. spadicea received from Mr. Cuming in 1862 is smaller than Reeve's figure, but resembles it in other- wise. Though labeled "Marquesas" it is apparently a form of P. elongata Pease, or very closely related to that species. Dr. Hartman has referred spadicea to P. t&niata; and the figure certainly lias a close resemblance to P. simulans Pse., a form of t&niata.
P. simulans Pease, based on shells which are "plain red- dish-brown yellowish or horn-color ' ' or with ' ' three inter- rupted transverse bands ' belongs apparently to t&niata. PI. 28, fig. 14 represents the cotype originally supplied by Pease for pi. 1, fig. 11 of the Am. Journ. Conch. It is not fully mature, and is corneous with indistinct brown streaks. It is this form which seems to be identical with P. spadicea Rve. PI. 29, figs. 8, 12 are uniform white and brown-banded examples also supplied by Pease at the time of original pub- lication. The banded examples have two submedian and one umbilical band, on a corneous-whitish ground. Some of these shells scarcely differ from P. t. nucleola.
P. striolata Pease, seems to be identical with t&niata ex- cept in coloration ; it is dull tawny-brown with a few whitish oblique streaks. The columellar tubercle is very weak, not prominent as in nucleola. Fig. 8, pi. 27, is drawto from a cotype received from Pease.
Whitish-corneous, solid shells, striped closely with brown or chestnut, chiefly on the last whorl (pi. 28, fig. 7) have been distributed by Garrett as striolata,. They are probably closer to the following form and to nucleola.
PARTULA, MOOREA. 209
Another race, tangent from nucleola, is figured, pi. 27, fig. 7. The dark brown shell is profusely striped on the last l1/^ whorls with cream-white. The columellar denticle is small and prominent.
P. T.ENIATA NUCLEOLA 'Pease' Garrett. PI. 29, figs. 14, 15, 16.
A small, compact, ovate-conic race. The surface is densely and distinctly striate spirally, but little shining, corneous- whitish, corneous-brown with wide indistinct darker and paler streaks, yellowish-brown or chestnut brown. The short spire is straightly conic; whorls about 4-°;4> the last full be- low, rounded or somewhat flattened on the back. The colu- mella bears a small but rather acute tubercle in the middle, at the lower end of the axial expansion. There is no parietal tooth, but sometimes the very slight indication of one may be seen.
Length 15, diam. 9, aperture 8.4 mm.
Length 16, diam. 8.2, aperture 8 mm.

This form is probably more primitive than the typical tceniata. It stands very close to P. filosa of Tahiti. The two are apparently of common origin. According to Garrett, nucleola intergrades with tccniata, yet it appears to be as distinct as elongata is. The largest examples measure 18 x 10, apert. 9 y2 mm. It lives in a small valley about two miles west of Opunohu.

appreciable in a basal view, as they cause the periphery to be irregular. The lip is like that of nucleola. There is a small nodule above the middle of the columella, and a small but iv ell-developed callous nodule or tooth on the parietal wall, deep within and near the columella.

Moorea (Mr. Geale).
The larger of the two shells in Dr. Hartman's collection (no. 4242 Carnegie Museum) may be considered the type of this 'form or race, if it be found racially separable from nucleola. The chief difference is the possession of a parietal tooth by corneola, which is wanting or only weakly developed in nucleola. The back of the last whorl is also somewhat more roughened in corneola. The smaller of the two speci- mens mentioned in the original account of "corneola" is identical with nucleola.
Fig. 15 represents the type; fig. 17 is a back view of an example in coll. Acad. Nat. Sciences, showing the wrinkles and the longitudinal streaking of the last whorl.
I suspect that P. concinna Pse. was based on a specimen of nucleola.

"The headquarters of this arboreal species is in Vaianai valley on the southeast coast of Moorea, where it is abundant, associated with P. lineata (= suturalis) and P. mooreana. It occurs, also, but in less numbers, in a valley to the west-

ward, where it is found in company with lineata and tcrniata. The same valley, which is about two miles from Vaianai, is the limit of the range of the latter species on that part of the island, and hybrids between it and elongata are rather com- mon, the same as between garrettii and thalia at Raiatea. To the eastward of Vaianai it ranges throughout the small val- leys for a distance of several miles, as far as Oahumi, the specific centre of strigosa." (Garrett).

This form seems to intergrade perfectly with P. taeniata, of which I would think it a subspecies, so far as I can judge without detailed study of the colonies in the field. However, Garrett writes "I cannot agree with Dr. Hartman in uniting this species with tceniata. It is only through hybrids between the two species that the inoscula- tion takes places. Examples taken in any of the valleys not inhabited by t&niata prove at once its distinction."
The type lot received from Pease contains three shells measuring
Length 18.5, diam. 9, aperture 9.3 mm., 5 whorls.
Length 17.2, diam. 8.8, aperture 9.2 mm., 4% whorls.
Length 16, diam. 8.1, aperture 8.9 mm., 4% whorls.
One shell is corneous-brown with inconspicuous narrow darker streaks, another is corneous-white with white streaks on the last whorl, while the third (fig. 6, and A. J. Conch, iii, pi. 1, f. 2) is dilute brown with indistinct, wide whitish corneous streaks. All have the dense, minute spiral sculpture of taniata and its allies. The whorls are not very convex, last one more or less flattened below the periphery, very con-

vex at base. The lip is narrowly reflexed, a little thickened within. There is no noticeable callous nodule on the colu- inella, and no parietal tooth.
Other lots show a wide range of variation in form and color, apparently showing considerable local differentiation. In one lot from G-arrett (pi. 29, figs. 1, 2, 3, 4, 5) there are several color-forms: tawny shells with narrow browner streaks (fig. 5) ; greenish white (fig. 1) ; pale brown or whitish with 4 in- terrupted bands (figs. 2-4). Another lot consists of yellow or yellowish-corneous shells, very indistinctly streaked (fig. 11). Still other forms (figs. 9, 10) approach closely to typi- cal P. tceniata, in color, having two widely separated whitish bands on a tawny-brown ground.

A thin little shell, writes M. Morelet, diaphanous, finely striate in both directions, recognizable by the obliquity of the aperture, the plane of which is inclined backward, as well as- by the angular shape of the last whorl. The peristome is di- lated, reddish at the edge, thickened by a white callus which is sharply limited towards the inside. The slightly curved columellar margin is applied over the umbilical region so as to almost wholly mask the opening.
Dr. Hartman referred this form to P. taniata, but the features noticed in Morelet 's remarks, translated above, hardly warrant such a disposition of it. The lip-color and
PARTULA, RAIATEA AND TAHAA. 213
the angle on the front differentiate P. erhelii from otherwise similar known Moorean forms. M. Morelet states that it was brought from Tahiti by M. Erhel, a young surgeon of the marine service who died in Senegal.
3. Species of Raiatea and Tahaa.
The Partulae of these two islands are so intimately related that they must be treated together. The separation of the islands by a shallow lagoon about two miles wide, has evi- dently been a quite recent event. Both islands are enclosed in the same encircling reef.
The extrinsic relations of the Partulae are with Tahitian forms. With the exceptions of P. turgida (no. 8) and P. attenudta (no. 17) already described, all Raiatean species may credibly be assumed to have descended from a single ancestral stock which was also the common parent of the otaheitana group. Subsequent events were as follows. (1) Three chief branches of this stock arose : the faba group, the dentifera group and the liebe group. (2) Each of these stocks spread over the available area, and (3) by local differ- entiation gave rise to numerous races, which are still doubt- less spreading and becoming further modified. This tertiary geographic radiation and racial differentiation was also ac- companied by an adaptive radiation whereby several arboreal forms gave rise to terrestrial species. As the result of these events we find most available stations occupied by two to four species, each representing one of the three stocks derived from differentiation (1), and from the adaptation to terres- trial conditions.
The comparative simplicity of the distributional conditions indicates that the evolution cycle outlined above has not been of great duration. By analogy with known cases, dif- ferentiation (1) probably took place in Pliocene time.
Most Partulge known to be terrestrial are from Raiatea and Tahaa, The terrestrial habit is no doubt a readaptation of arboreal ancestors. The eoloration approximates to the dull tints of ground snails.
214 PARTULA, RAIATEA AND TAHAA.
Group of Partula dentifera.
These arboreal snails of Raiatea and Tahaa are character- ized by the usually light yellow color of the shell, the sum- mit white, yellow, pink, or purple-tipped; lip white, thick- ened within, more or less strongly toothed within the outer lip and excised above the tooth. Columella and parietal wall often toothed. The species are closely related to some of the faba group.

b. Lip heavy, keeled on the face, with a heavy tooth above ; no columellar or parietal teeth.

Properly speaking, this group consists of only three species : P. callifera of Haamoa valley, Raiatea ; P. solidula of unknown locality, and P. dentifera, of which formosa, citrina, imper- forata and virginea are scarcely more than subspecies, spread over Raiatea and part of Tahaa. P. imperforata raiatensis and virginea are apparently the least modified survivors of the original stock.

This may be identical with one of the described forms of P. dentifera or imperforata, such as virginea, or more likely raiatensis; but perhaps representing another race of the same stock, not rediscovered by Mr. Garrett. Pfeiffer's figures evidently do not apply to -exactly the same form. Hartman expressed the idea that solidula is a large form of P. lutea. Garrett compares solidula to compacta Pse., from which it differs by the parietal tooth. Description and figure from Reeve.

Aperture slightly oblique, narrow, obversely ear-shaped. Peristome white, strongly thickened, built forward; its margins sub- parallel, the right margin deeply curved above, and bearing a strong, acute, tooth-like tubercle in the middle. Length 211/4, diam. 10, aperture 11 mm. (Pfr.).
Raiatea: The specific centre of the type of this species is in the large valley of Vairahi, on the east coast of Raiatea, where it occurs in vast numbers on foliage in company with the typical P. hebe. It has not spread at all to the south- ward, but a variety occurs in an adjacent valley on the other side. ( Garrett} .

It may be distinguished by its elongate-conical form, straw- yellow color, rather shining surface, chink-like perforation, and small oblong obauriform white aperture. The peristome is ivory-ivhite, heavily calloused, the face angularly ridged, strongly labiated within, and armed slightly above the middle with a very prominent tooth, above which the lip is strongly contracted, forming a conspicuous sinus. A very rare variety occurs of a ruddy brown color, purple-black apex, and flesh- colored peristome. Examples with a white sutural line are not infrequent and most shells are a little paler below the suture ; otherwise it is never ornamented with bands ; even the most perfect specimens always have the cuticle more or less decorticated behind the peristome, which suggested the provisional name decorticata. The above notes, slightly modi- fied from Garrett, apply to the typical P. dentifera from Vairahi valley, of which P. labiata Pease (fig. 9) is an exact synonym. In this form a parietal tooth is never developed. The color varies commonly from straw to light greenish yellow. The figured shell (fig. 9) measures, length 21, diam. 11, aper- ture 12 mm. but it is sometimes as small as 19 mm. long.
Garrett states that north of Vairahi valley, P. dentifera ;'has migrated into a small adjacent valley, where it is much less abundant, and differs from the type in about half of the specimens having a prominent parietal tooth (which is al- ways absent in examples inhabiting Vairahi) ; otherwise the shells are not dissimilar. ' ' Examples of this dentate race are figured pi. 20, figs. 7, 8. It certainly approaches close to P. imperforata raiatensis.
P. dentifera is never banded, and the apex, though often yellow, is never rose-colored, as it often is in P. imperforata.

"Shell large, imperf orated, solid, elongate-ovate, striated, shining, pale yellowish white, straw-yellow or fulvous; spire conical, with nearly flat outlines, spirally striated with fine, crowded, incised lines, half the length of the shell, and fre- quently tinged with rose-red ; suture slightly impressed, mar- gined with a rugose, white line ; whorls five and a half, flat- tened, the last one large, convex ; aperture oblong, subvertical, obaurif orm ; peristome white, rather widely expanded, decliv- ous, external margin angularly ridged, inner margin strongly labiated, acutely dentate, and contracted above the denticle; parietal region thinly glazed, edentate ; columellar lip closely appressed over the umbilical region. Length 25, diam. 13 mm. (Garrett).
The metropolis of this very distinct species is in Fatimu, or on the southwest part of Raiatea. It occurs in vast num- bers on bushes on the lowlands near the seashore, becoming more scarce inland, where it is found associated with P. hebe, var. bella. It ranges north as far as Vaiau valley, be- coming less and less abundant as the distance increases from its specific centre. (Garrett).

"Its large size, edentate parietal region, sharp labial tooth and closed umbilicus will readily distinguish it. It is never ornamented with bands. ' ' The columella is slightly sinuous, but has no distinct tooth or nodule such as is present in P. imperf orata.

This species stands very close to P. dentifera and P. im- perforata. It differs from dentifera by the flattened or in- wardly sloping lip, which is not keeled on the face, by the less prominent tubercle within the outer lip, and by the more emphatic nodule on the columella. Compared with P. im- perforata, it differs by the absence of a parietal tooth, the usually lighter color, larger size and slightly open umbilicus, all being inconstant characters. Garrett writes as follows: "Though considered by some authors to be a variety of P. faba, I am, nevertheless, fully convinced of its specific value. When I first discovered it in 1861, I took but few examples, in consequence of not penetrating far enough into the valley to find its headquarters. A more extended research in 1873
220 PARTULA, RAIATEA AND TAHAA.
revealed its specific centre, and I took about eight hundred specimens in various stages of growth, and many of the adults were in a gravid condition.
"It has been suggested that it may be a hybrid be- tween faba and some other species, I only noticed faba and garrettii in the lower part of the valley, and not in the upper portion, which is the principal haunt of citrina. Its uniform straw-yellow -color, more slender form, smaller perforation, more reflected columella, and more decided labial tooth, and profounder emargination, will distinguish it from the very variable faba.
"My largest examples are 25 mill, in length and 12 in dia- meter. It is always of a straw-yellow color, rarely with faint longitudinal darker strigations, and is either lemon-yellow or light red at the apex. It is never spirally banded, and the parietal wall is invariably edentate. The oblong white aperture is, including the peristome, half the length of the shell. The ivory-white lip is broadly expanded, planulate, declivous, strongly labiated, slightly dentate and distinctly emarginate above. The slightly gibbous columella is re- flected over the small compressed perforation."

Spire conical, with subplanulate outlines, about half the length of the shell ; suture sometimes margined by a rugose white line ; whorls 5-5 y2, flatly convex, the last one convex, or convexly rounded. Aperture sub- vertical, oblong, obaurif orm, white, sides nearly parallel ; parietal wall with a more or less developed tubercular tooth; peristome white, thick, moderately expanded, its face con- cave, heavily labiated within, strongly contracted above, form- ing a rather profound sinus, and generally subdentate next to the emargination; eolumellar lip subnodose.

"Like all the species, they differ some in size, shape, and some have the spire more abbreviated than others. The type, which inhabits Hapai valley, is nearly always imperforated and may be distinguished from the imperforate formosa by its smaller size, gibbous columella and parietal tooth. Car- penter confused it with dentifera, an allied species confined to the opposite side of the island" (Garrett).
Garrett 's description, slightly modified, is given above. His figured cotype and two others of the same lot are illus- trated, pi. 20, figs. 13-15. The length varies commonly from 19 to 21 mm., diam. usually 11 mm. It differs from P. dentifera by the smaller tooth in the outer lip, by having a more or less distinct oblong callus lump on the columella near its insertion, and a small parietal tooth (sometimes ab- sent) ; the face of the lip is less thickened than in dentifera. It is a less evolved race than dentifera.
Typical imperforata is confined to Hapai valley. The valley Toloa is inhabited by a weakly individualized local race which has been called raiatensis Garrett (pi. 20, figs. 16, 17) and recta Pse. (in coll. 1863) not P. recta Pse. 1868. Gar- rett writes: "After a careful study of about 2000 specimens of the two species, I have annexed the Toloa with the Hapai shell. The only difference between the two is that raiatensis is usually lighter-colored, seldom imperforate, and the apex is
222 PARTULA, RAIATEA AND TAHAA.
much more frequently rose-red. It is, I think, more nearly related to the dentated virginea, inhabiting the neighboring island, than to dentifera." This conclusion is fully sup- ported by the series before me, received from Pease, Garrett and others.
26a. P. i. VIRGINEA 'Pse.' Garrett. PI. 20, figs. 18, 19.
"Shell compressly umbilicated, solid, oblong-conic, some- what shining, yellowish corneous or light fulvous brown; spire convexly conical, half the length of the shell; suture margined by a whitish line; whorls 5-5^, slightly convex; aperture subvertical, oblong, obauriform, rounded below and much contracted by the strongly labiated peristome ; parietal wall with a white tubercular tooth which is rarely absent; peristome white, sometimes tinged with carnelian, widely ex- panded, subplanulate, slightly contracted above, and the mar- gins frequently nearly united by a ridge of callus; colu- mellar lip vertical, more or less distinctly nodose. Length 18, diam. 9 mm." (Garrett).
"Form a. Uniform chestnut-brown. Not uncommon.
"Form fe. Yellowish corneous, with a basal and sutural chestnut-brown band. Very rare." (Garrett).
Raiatea: The specific centre is in Vaipiti valley, on the west coast of Tahaa, where it occurs in the greatest pro- fusion on the foliage of shrubs. It has extended its range to the northward as far as Murifanna on the north coast, which latter is the limit of the western range of P. umbili- cata. (Garrett).

This form is practically identical with the raiatensis form

of imperforata. Although I give Garrett's description above, I am convinced that no study of descriptions or of the type specimens, which I have 'before me, would enable one to separate a series of the two forms if mixed. The distinc- tion is based chiefly on geographic distribution but also to some extent on the diverse variations of the two forms. Pale specimens of virginea usually have the apex purple- tipped (not pink, as in raiatensis} ; but the darker shells have the embryonic whorls white. The only closely related or similar shell on Tahaa is P. planilabrum, which belongs to the faba series.

to the northward, where it is found, though less abundant, in an adjacent valley, associated with the typical P. dentifera. About two miles to the southward, on the same side of the island, in a large valley called Opoa, is found in large num- bers the pretty variety bella Pse., which has passed over a range of wooded hills into a large valley on the south coast, where it occurs in limited numbers in company with P. for- mosa.

Typical P. hebe (pi. 21, fig. 1) has the shell covered with a very thin white more or less shining cuticle, upon which delicate spiral lines may be seen under the lens. Most ex- amples have lost their cuticle and have a matte white sur- face (figs. 2, 3). The size and proportions vary but little, the usual size being, length 15, diam. 10.2 to 11, length aperture 8.2 to 8.8 mm.
The outer lip is rather narrow in the typical form ; in the heavy, denuded examples it is wide and heavily thickened within, generally showing a trace of the tooth or tubercle above the middle which is so prominent in the related faba group. It is often thickened on the face and convex or carinate there. The columella in oblique view in the aper- ture, is very wide.
This charming snail has several close relatives among the dull ground-living species, such as P. crassilabris etc.
PARTULA, RAIATEA AND TAHAA. 225
P. HEBE BELLA 'Pse.' Hartman (pi. 21, figs. 4, 8) has the spire orange rose colored, usually darker towards the apex. The surface is glossy, covered with a very thin yellow cuticle which is usually deciduous in part, or is entirely lost, when the whole surface is lusterless. The shell is often more solid than typical P. hebe. This form was named P. globosa and P. h. bella by Pease many years ago, but it was in no manner described until Dr. Hartman reported on Pease's duplicates.
I am unable to find much cause for recognizing var. ventricosa Garrett, 1884 (pi. 21, figs. 6, 7). It "is usually a little smaller than the type, not decorticated, and is more variable in color, but never banded. The ground color varies from whitish to fulvous, rarely with a reddish spire, but more frequently with the apex of a purple-brown." (Gar- rett}. The cuticle is decidedly thicker than in other forms of hebe; it peels off in an area behind the lip, but is else- where persistent. The parietal tooth is smaller than in other forms of hebe. Figured from examples received from Grar- rett. This form is probably what Dr. Hartman refers to as "P. ventrosa Pse." (t. c., p. 193). It approaches P. cras- silabris, a ground species, but differs by its much larger parietal tooth, etc.

The shell is umbilicate, short, ovate-conic, moderately thick. Surface rather dull, lightly marked with growth-lines and usually showing engraved spiral lines distinctly on all the whorls; brown or corneous-brown, the base darker, spire or apex usually purplish-brown; periphery frequently (and typically) encircled with a yellow belt or line. The conic spire has straight sides; whorls 4%, only slightly convex, the last rotund. The aperture is small, rounded-ovate, dark flesh-colored inside. Peristome expanded, thick in adult shells, thickened within, its face convex, white, or brownish towards the outer edge. Outer lip is a little narrower above, but not dentate ; at the insertion it gives off a short parietal

Raiatea : The metropolis of this species is in Hapai valley, on the west coast of Raiatea, the home of P. imperforata and lugiibris. It is very abundant, lurking beneath decay- ing vegetation and found associated with the typical form of P. lugubris. It has not spread any to the northward, but to the southward it has migrated into two small ravines. (Garrett).

This small ground-snail is very closely related to P. hebe. It differs from that by the dull brown color, smaller parietal tooth (which indeed is sometimes wanting), the less ex- panded lip, and persistent cuticle.

Raiatea: The metropolis of this species is in a large valley called Toloa, on the west coast of Raiatea, where it occurs in great abundance beneath decaying vegetation. It has migrated to the southward into two small adjacent val- leys, but does not extend its range so far as Hapai, the next large valley, and the home of the allied P. crassilabris. (Garrett] .

Described from Pease's type lot, no. 59480 A. N. S. P. Garrett writes as follows: "It is larger, less globose, the aperture more oblong, than P. crassilabris with which it has been confounded. Its chief character consists in the colu-
228 PARTULA, RAIATEA AND TAHAA.
mellar region 'being, as it were, pressed in towards the aper- ture, nodulous on the inner margin, and subangulated at the base. The parietal tooth is less developed and absent more frequently than in crassilabris. The coloration is the same in the two species. Like the majority of the ground species, it varies in a greater or less degree in shape and size. Some forms almost exactly simulate P. garrettii, not only in the out- line of the shell, but in the peculiar shape of the aperture as modified by the columella being pressed inwardly. Occa- sionally examples occur which are so much abbreviated that they resemble P. crassilabris, but may readily be separated by the dissimilarity in the columellar region.
"My P. pinguis, of which I have seen only a dozen ex- amples, was found under decaying leaves in the mountain ravines, at the head of Vaioara valley. It certainly equals rustica." (Garrett).
30. P. GARRETTI Pease. PL 21, figs. 15 to 19.
The shell is minutely rimate or imperforate, oblong-ovate, solid and strong, slightly shining, lightly marked with growth-strife and minute engraved spiral lines, which are usually more or less obsolete on the last whorl; yellowish, the spire either paler, apex white, or spire pink-tinted with the apex purplish flesh colored. Suture very lightly impressed, edged with a white line. Whorls 5, very slightly convex. Aperture is oblique, white within. Peristome very narrowly expanded, thick, the face convex or keeled, pure white ; in- ternal rib strong.

Differs from the related P. thalia and P. nistica by its less inflated form, extremely narrow or closed umbilicus, less expanded lip and strongly developed columellar sinuosity. Garrett remarks that "Its principal characters are its small size, contracted aperture, rounded or angulated peristome and nodulous columella, which latter is, as it were, pushed in towards the aperture. The parietal region is very rarely toothed. It is whitish or pale yellowish horn-color, rarely fulvous or light brown, and sometimes the apex is purple- brown. A variety with a brown base and sutural band is not infrequent."

Tahaa : The metropolis of this well-defined species is in a large valley called Haamene, on the east coast of Tahaa, where they are found in prodigious numbers on the foliage of low bushes. It has not spread any to the southward, but, on the other hand, ranges in considerable numbers through all the valleys, except Faa-apa, the home of bilineata, as far as Murifanna on the northwest coast, where it is found asso- ciated with P. virginea.

P. umbilicata unites characters of the auriculata and the rustica groups in some degree, though nearer rustica, of which it might be called a very large and obese edition. The outer lip is a little narrower in its upper fourth than in P. thalia, and there is a distinct callus, often dentiform, superposed upon the columella. The parietal tooth varies from small to well developed, and seems to be invariably present. There is often an indistinct appearance of several angles in the out- line of the outer lip, which is moderately expanded, and cream-white behind, white on the face. The whole surface generally shows spiral strias. Umbilicus much wider than in P. thalia. The last whorl is typically well inflated, but I have seen specimens with a strong peripheral angle, from retention of a juvenile character in the adult stage.
Color various; the commonest pattern before me is chest- nut, fading to yellowish-white below the last suture, gradu- ally shading to purplish-black at the apex ; but sometimes the whole shell is straw-color. In fig. 11 it shows one of the common color-patterns of the faba group. Figs. 13, 14 rep-

A dull, streaked species, with "key-hole" aperture, the outer lip having a prominent tooth projecting inward, above which it is very narrow. The parietal tubercle is variable, but usually present. Apex may be either white or blackish- brown. Length 20 to 22, diam. 11. Length 21, diam 11.5 mm. It was first described by Garrett, in 1884, although Hartman had given a brief descriptive note in 1882 (Bull. M. C. Z., ix, 185, 196). It was widely distributed by Pease, and in consequence of an ill-judged identification by Cuming and Carpenter, has generally been known in collections as "P. compressa Pfr." Garrett 's type, no. 59409 A. N. S. P. is figured, fig. 5. Others from Pease (fig. 6), Hartman and others are before me. P. radiata stands very close to P. fusca approximata of the,, southern part of Raiatea, but it is duller, with a larger lip-tooth and generally it has a parietal tooth. In the several forms of P. fusca, the parietal tooth, when present, is not so large as in radiata.
A form which Pease called P. microstoma (in his collection, 1863), and which inhabits Vairahi valley, "though very fre- quently found adhering to the lower portion of the trunks of trees and shrubs, can scarcely be separated from radiata, which is strictly terrestrial in habit. Dr. Hartman unites it with P. vittata. It appears to me more nearly related to radiata than the latter, which is smoother, and the columellar lip is flat and simple." (Garrett).

received from Hartman. It measures, length 23.7, diam. 13, aperture 12.2 mm., has the shape of radiata, but the tooth within the outer lip is less developed. There is no parietal tooth. The base of the last whorl and a band below the suture, ascending the spire are chestnut, leaving a rather wide pale buff zone. The surface is not quite so dull as in radiata. Whether this form is identical with Garrett's Vairahi microstoma remains uncertain. The discussion be- tween Hartman and Garrett about the identity of Pease's microstoma is academic, since Pease never described the form. It was first described (by accident, and quite unrecognizably) from Hartman 's collection, by H. H. Smith, as cited above.
According to Garrett, specimens which he regards as hybrids between P. radiata and P. fab a are of common occurrence.

This is a very thin member of the faba, group, deficient in lip callus and teeth, smaller and more lightly built than P. fusca, which is also a ground snail.
The race described by Pease as P. ovalis (pi. 19, fig. 7) differs from lugubris only by being a little larger, more solid, with a stronger lip-callus. It replaces lugubris in Vaiau valley, the typical lugubris being confined to Hapai valley. It approaches very near to P. vittata, which is a larger form with longer spire and a small parietal tooth. The ovalis form is usually dark chestnut with a yellowish belt, but sometimes is of a uniform chestnut hue.
Mr. Garrett writes: "My largest Vaiau specimens are 20y2 mm. long, and 11 mm. in diameter. The smallest adult from Hapai is 16 by 8 mm. I have found hybrids between lugubris and imperforata, the latter a strictly arboreal species.
"Dr. Hartman, overlooking the fact that lugubris, ovalis, protea and fusca inhabit widely separated valleys, has sug- gested that the three former may be the juvenile and adoles- cent forms of the adult fusca. The habitats of the two former species are about two miles apart, and five miles south of the location of fusca. P. protea, which = fusca, is confined to the opposite side of the island, and is separated from the lat- ter by an almost inaccessible mountain."

P. faba was first obtained when Captain Cook visited Raiatea in 1769. Andrew Garrett writes as follows:
' ' The type varies from straw-yellow to brownish yellow or fulvous, with a broad basal and narrow sutural chestnut- brown band. The most common bandless variety is of the normal color varied with longitudinal darker strigations. A variety of a uniform, whitish horn-color, as well as one of a uniform chestnut-brown, sometimes approaching black, is not infrequent. The lip is white, and the apex frequently tinted with purple-black.
They vary considerably in shape, as the following measure- ments will prove :
Length 25, diam. 14 mill.
Length 25, diani. 12 mill.
The average dimension is 25 *by 13 mill. Out of about 6000 examples I found but one possessing the parietal tooth. Hybrids between this species and radiata, fusca and naviga- toria are not uncommon."
Fig. 1 is a copy ot Martyn's type figure. Fig. 2 is a more streaked example of the typical form. Deep brown (fig. 3), and greenish-yellow (fig. 4), examples are also drawn. Figs. 5 to 8 are from a series collected by C. D. Voy, presumably in one colony, the several color-forms being connected by inter- mediate stages.
P. subangulata, amanda, navigatoria and fusca might be ranked as subspecies of faba without going far wrong.

The pale subsutural band gives the shoulder an appearance of angulation, which does not really exist. While the Tahaan forms of the faba type differ but little from Raiatean faba, yet their variation-forms are somewhat diverse, and the minor differences noted above seem fairly constant. I have therefore thought it best, in view of the minute specific subdivision of Raiatean Partula?, to give subangulata specific rank.
36a. P. s. AMANDA Garrett. PI. 17, figs. 1, 2, 3.
The shell is like subangulata in shape, but it occasionally has a small tooth on the parietal wall. The usual color is pale yellow or greenish yellow, almost white towards the summit, or more or less suffused with fulvous, with a white or flesh-tinted lip. "A beautiful variety occurs which has a wide median reddish chestnut band (fig. 1). A more common variety is found with two narrow reddish chestnut bands" (fig. 2) ; the summit in these is purple-black. '"Chestnut- brown varieties are not uncommon. The rarest variety is fasciated the same as the typical faba." (Garrett).

A subvariety of amanda has been called var. dubia Garrett (pi. 17, figs. 4, 8) but that name was already in use for a Tahitian form of the otaheitana group. It is yellow with a white spire, white lip, and invariably has a parietal tooth. Some specimens have a chestnut umbilical area, or are some- what suffused and streaked with fulvous, and the apex is pinkish brown. This form is found in some valleys on the north coast.

This form differs from P. faba chiefly by having the last
two whorls less convex than usual in that species, and the
aperture is narrower, more contracted. Moreover it lives for
the most part on the ground, and has its own patterns of
• coloring, which however do not differ much from the patterns

of faba and fusca. Garrett writes that "hybrids between this species and fusca and faba are very frequent."
The typical coloration of navigatoria (fig. 9, copied from Reeve) and the synonymous varidbilis is yellow, profusely streaked with chestnut, the spire often pinkish. This is the normal or usual form. Other patterns are:
Uniform yellow. Not common.
Uniform dark chestnut, or with pale apex. Not common.
The last form, greenish yellow, the base and a subsutural band chestnut, is not uncommon; it resembles typical P. faba in pattern.
' ' The parietal tooth mentioned by Pf eiffer, but not alluded to by Reeve or Pease, is not constant, but exists in about two- fifths of the adults. The former author's 'medio subden- tato,' likewise not mentioned by the latter two writers, is simply the lower angle of the small labial sinus.
"In shape it varies from ovate to oblong-ovate, as the fol- lowing two measurements will show: Length 25, diam. 13 mm.; length 20, diam. 13 mm." (Garrett).

"The above is about the average dimensions. My largest example is 24 by IS1/!* and the smallest adult 17 by 10 mm. Sometimes, though rarely, the spire equals half the length of the shell.

Raiatea: The metropolis of this very variable ground species is in Vaioara valley, on the west coast of Raiatea, the headquarters of P. garrettii and navigatoria. It has not migrated any to the southward, but to the northward it oc- curs sparingly far up in Huaru valley. On the opposite side of the island it is found in Tepua valley, and I took a few in a small ravine more to the southward. The Tepua shell, which is the protea Pse., differs none from his fusca. (Garrett).
' Hybrids between protea and the arboreal P. faba are not uncommon, and are usually found adhering to the lower parts of the trunks of trees.
'In Vaioara, hybrids between fusca and navigatoria, and between the two former and faba, are so frequent as to be very embarrassing in the separation of the three species col- lected in that valley. Like the Tepua hybrids, all those be- tween the two ground species and the arboreal faba live on the lower parts of the trunks of trees." (Garrett).

Illustrated from specimens received from Garrett. Others from Pease are before me. This snail lives under cover on the ground, and the shell is less glossy than navigatoria or faba which differ from fused and vittata chiefly by their arboreal habits and brighter shells. The lip is usually expanded more than in vittata, which replaces fusca on the southwest. P. fusca occasionally has a small parietal tooth, 'but in vittata the tooth is almost invariable in fully adult shells.
38a. P. F. VITTATA Pease. PI. 17, fig. 16.

The ample, oblong aperture is 'considerably contracted by the intrusion of white callus on the inner margin of the peristome, and the sides are nearly parallel. The peristome is rather thin, widely expanded and usually stained with brownish purple. The white callus does not extend to the upper end of the lip, leaving a shallow sinus. The columella is flattened, not calloused or nodose, and reflected over the umbilicus. The color is whitish, yellowish corneous, fulvous or horn-color, fre- quently with the basal third of the 'body and a sutural band chestnut-color. Sometimes the apex is 'black or purple-black. The parietal tooth, though small, is constant, 'but so far within that it is hardly visible in a front view.

Doubtfully distinguishable from P. fusca. The figure is drawn from the shell already figured by Garrett, who col- lected the type lot.

This is a race subsidiary to vittata characterized by its inferior size, smaller umbilicus, which is frequently imper- vious, smaller aperture, and less expanded lip. The parietal tooth is very seldom developed. The banding is similar in the two forms, but occurs rarely in approximata, which dif- fers also in being generally a lighter or darker chestnut-color, though both have similar horn-colored varieties, with brown streaks. The last whorl is usually angular in front, as in var. terrestris.
Occurs in greater or less profusion in several small valleys on the southwest part of Raiatea.
Cotypes from Garrett are figured.

The shell is moderately umbilicate, thin, with only a trace of spiral striae on the last whorl. It is (1) corneous with yellowish streaks, (2) chestnut colored, or (3) chestnut with an equatorial yellow zone. The apex is usually pale, but sometimes purple. The last ivhorl is rather acutely angular immediately in front of the upper termination of the outer lip ; or if not, an angle may 'be traced above the suture, near the aperture; the immature stage being strongly angular. The aperture is rather narrow, with a distinct prominence at the upper end of the lip-callus. Lip moderately expanded,

Differs from P. vittata chiefly by the distinct angulation of the 'body in front of the aperture. Gotypes in coll. A. N. S. P., no. 59450. Garrett writes:
"In the valleys on the southern part of the island (Raiatea), we find a gradual change from the typical P. ap- proximata into the form known as P. terrestris Pease, which latter connects the former with vittata. The range of ter- restris terminates at Opoa valley, on the southeast coast.
"At Faaloa, on the east coast, there exists a form, P. cas- tanea Pease, which is intermediate between terrestris and vittata. It is usually chestnut-colored, constantly toothed on the parietal wall, and the fasciation is the same as in the other varieties. It has not spread any to the northward of Faaloa, but occurs more sparingly in a small valley between Faaloa and Opoa." (Garrett). A specimen of castanea received from Pease is figured (pi. 17, fig. 12). It is absolutely iden- tical with terrestris.

The callous rim and "tooth" within the outer lip are more strongly developed than in P. faba, fusca and their immedi- ate allies. There is an oblong callous lump on the face of the columella, more or less visible in different examples. The white border below the suture is an important feature of the species, very rarely wanting. P. planilabrum is larger and more elongated than P. bilineata, and the surface is not so smooth and shining. The structure of the peristome is similar in the two shells, but the aperture is more elongate in planilabrum. The parietal tooth is constant in adults but varies in size. The following color-forms are found.
PI. 18, figs. 2, 3. The type is deep chestnut-brown, gradu- ally fading into yellowish corneous towards the sutural line; the whitish lip is •frequently tinged with violet.
PI. 18, fig. 4. Fulvous yellow, with the basal half of the body- whorl and a revolving band below the whitish subsutural border, deep chestnut-brown. Not infrequent.
PI. 18, fig. 1. Pale corneous or light fulvous with indis- tinct oblique streaks. Rare.
Numerous specimens from Pease and G-arrett show it to be rather constant in form, but some shells show an angle on the last whorl, in front of the aperture. Garrett writes: "The metropolis of this species is Haamene valley, on the east coast of Tahaa, where it is common, and, though usually lurking beneath decaying vegetation, is sometimes found ad- hering to the trunks of the wild banana. It is found, though less abundant, in a valley north of its specific centre, but does not occur in the intermediate valley Faa-apa, the home of bilineata."

pale yellow or brownish yellow, typically with a narrow brown band revolving a short distance below the suture, and a wider one just below the perifery; but sometimes the whole base is dark chestnut, or the whole shell may be dark except for a light equatorial girdle or zone. The aperture is nearly white inside, lip broad, white, well expanded and strongly thickened within. The columellar lip bears on its inner face a low nodule, sometimes hardly noticeable. The parietal tooth is deeply placed and well developed.

P. plamlabrum is more lengthened and less glossy than bilineata, and the two have not the same cycles of color-forms. P. umbilicata is a still more shortened and globose form. These three species of Tahaa are slight modifications of the ancestral Raiatean P. auriculata stock. Fig. 14 represents Pease's type specimen. Garrett writes of P. bilineata,: "It is readily distinguished by its smooth, glossy surface, ovate- conic form, yellowish horn-color, and two revolving chestnut- brown bands, the upper one narrow and subsutural. The subacute apex is sometimes purple-brown and the suture is margined by a narrow, rugose, whitish line. The constant parietal tooth is prominent and the 'broad white peristome is slightly emarginate above, strongly labiate within, and widely expanded.

This arboreal species is obese, solid, not very glossy, with a moderate or quite narrow umbilicus. The lip is not very broadly expanded, 'but is strongly thickened within, white, flat, often more or less dentate, and is conspicuously excised above. The columella is oblique, broad, and bears a moder- ate or heavy callus which is notched at the insertion above. The parietal tooth is well developed.

P. auriculata has been united by many authors with the totally different P. otaheitana of Tahiti. The erroneous locality "Huaheine" was given by Cuming, who collected the types. As Pease and Garrett have already remarked, P. auriculata was evidently based upon several forms of this group, but the emphasis laid by Broderip upon the flat lip indicates that the form described as P. compacta by Pease is practically typical auriculata. Reeve's Conchologia Iconica, Partula plate 2, figure 11& may be considered the type of P. auriculata. I have figured similar shells, pi. 18, figs. 10, 11. The color is usually light brownish yellow, 'but it varies to light chestnut in the lots before me. Fig. 9, copied from Reeve's figure of one of the original lot, is unlike the com- pacta I have seen in being banded. Pease's type of com- pacta, now before me, is a typical auriculata in develop- ment of the apertural callosities. In many individuals the "teeth" are less developed, as in fig. 8.
41a. P. A. ROBUSTA Pease. PI. 18, figs. 13 to 16.
The shell is somewhat smaller than the largest P. auriculata,

more compactly ovate, very solid, the lip very little ex- panded and very much thickened on the convex face, though less broad than in auriculata, and with less prominent in- ternal callosities, hence the aperture is more open. The parietal tooth is smaller than in auriculata, and often almost disappears. The lip is generally brown-edged, and often a raised callus connects the ends. The columellar lip is seen, in profile view, to be very thick, and the umbilical crevice is narrow. Color-patterns as follows:
a. Last l1/^ or 2 whorls corneous, copiously streaked ob- liquely with chestnut; the next earlier whorl rich chest- nut, deepening to purple-black towards and at the sum- mit. This is the typical coloration.
5. Yellowish, with some faint brownish streaks, apex pale. Approaches auriculata in form.
c. Dark chestnut throughout, with more or less distinct paler oblique streaks on the last whorl.

4. Species of Huaheine.
Huaheine possesses four species all endemic. Two (P. arguta and annectens) are restricted to two valleys, and the latter, like P. clara, appears to be gradually becoming extinct. Both species are remarkably uniform in all their specific characters, and are related to forms of Tahiti and Raiatea. On the contrary, the other two species (P. rosea and varia) have spread nearly all over the island, and are subject to considerable variation. Neither is closely related to other Society Island species, but a form scarcely distinguishable from varia occurs at Rarotonga. It is worthy of remark that
250 PARTULA, HUAHEINE.
dentated species, which are so common in all the islands ex- cept Borabora, do not occur on Huaheine.
The structure of the kidney raises a doubt as to the sys- tematic position of P. rosea and varia. They may belong in or near the section Samoana rather than to Partula s. sir.

PARTULA, HUAHEINE. 251
This common Huaheine species is smaller and more glossy than P. rosea, and differs in its range of color-variation. Ac- cording to Andrew Garrett, the type form "is very variable in coloration, and considerably so in size and shape. The smallest form, which = = P. pulchra Pse., gradually merges into the type, and is restricted to the larger of the two valleys called Hamene. The type which equals my huaheinensis and adusta, is usually corneous, luteous, more frequently fulvous, rarely white, and the most abundant variety is dark chestnut, sometimes nearly black with a pale apex and dark or pale lip (fig. 1). Deep chestnut-colored examples, with a wide or narrow central pale band, are not uncommon (fig. 2). The form with an obscure central fulvous band on a pale ground, is rather common (figs. 6, 7).
"In the higher portion of Hamene may be found a large form (bicolor Garr., not of Pease) which is either uniform straw-yellow, or greenish yellow, with or without a dark chest- nut spire. It differs from the typical varia in being larger, more robust, the whorls more inflated and the aperture wider. Specimens from Garrett are figured, pi. 23, figs. 4 and 8.
"In a valley named Faahiti, on the northern part of the island, we find in the greatest profusion, associated with P. rosea cognata Pse., a form shaped like ' bicolor,' but smaller and more variable in color than the typical varia. The most -common variety is light yellowish, sometimes stri- gated, the lip, and sometimes the base, stained with burnt- brown or violet-brown. Nearly half of the specimens are uniform fulvous brown, or chestnut-brown approaching black. The variety with central pale band is also very frequent, as well as the one of a uniform whitish or luteous with white lip. The pale variety with chestnut spire is somewhat rare, besides one with a dark spire and two narrow bands on the body- whorl. A lot of these shells sent to the 'Museum Godeffroy,' were by Prof. Mousson referred to Morelet's P. simplaria, and have been freely distributed under that name. Morelet cites 'Tahiti' as the habitat of his species. His 'apice obtuso rosaceo' and 'sutura albo marginata' do not occur in these
252 PARTULA, HUAHEINE.
shells, nor any of the varieties of varia" hence the name simplaria should not be applied to them. Specimens of various color-patterns are figured, pi. 23, figs. 9, 10.
The form called P. glutinosa Pfr. is straw colored or pale fulvous, the lip white with a purplish-brown border. It was originally described as from the Solomon Islands. Fig. 11 is a copy of the original figure. A specimen received from Cuming is drawn in fig. 15. "P. perplexa Pse. MS." of H. H. Smith is the same.
P. mucida Pfr. was based on the uniform chestnut colored form of varia. A figure of the type specimen in the British Museum is given, pi. 41, fig. 13.

The shell is openly perforate, rather thin, ovate-pyramidal, moderately glossy ; under a lens it is seen to be marked with fine growth-lines and close, waved, distinctly engraved spiral lines. Whorls 5, very slightly convex, the last generally angular at the periphery, in front of the aperture. The aper- ture is ovate, slightly oblique ; outer lip well expanded, thin- edged, strengthened with 'a narrow callous rim within, gradu- ally tapering to the upper end. Columella thin, dilated above.

The typical color (pi. 22, figs. 1, 2) is uniform rose, in- cluding the interior and lip ; but in many examples the em- bryonic whorls are paler or yellowish with a pink sutural line.
Huaheine : ' ' The headquarters of this beautiful and well- known arboreal species is in a large forest at the head of Hawai bay on the west side of Huaheine. From this region, where they are very numerous, they have spread over many parts of the island. They differ but little in .shape in the different localities, except in Faahiti on the north coast, where they (the P. cognata Pease) are smaller, less angulated on the last whorl, and in the total absence of the uniform dark purple-brown and rose-colored varieties which are so com-

Besides the common typical rose-colored form (figs. 1, 2), the following color-patterns occur. From Garrett's remarks it appears that several of the patterns occur together, so that they seem ordinarily to have no racial status. The some- what smaller form cognata seems to have incipient racial features.
2, form purpurascens Pfr. Dull purple, the aperture and lip violet, common (fig. 3).
3, form bipartita. Upper surface rose (fig. 4) or purple (fig. 5) base pale yellow, the lip white. "Frequent in the metropolis of the species but very rare elsewhere " (Garrett) .

white (figs. 8, 9). According to Garrett this form is very abundant.
6, form zotiata. Yellow, with the base and a narrow or rather wide sutural band brown, purple-brown or rose-color, mouth bicolored. Common (fig. 10, 11). Varies in size from 24 x 13.5 to 21.5 x 12.5 mm.
7, form cognata 'Pse. ' Garrett. Often smaller, length i9.5 to 23 mm., yellow with the suture tinted with rose or purplish; aperture white (pi. 22, figs. 12, 17; pi. 33, fig. 3), "Very common in Faahiti valley, but rare elsewhere" (Gar- rett). This small form varies to light yellow with pallid spire, and to yellow with purple or roseate spire, like form bicolorata ; or it may have the color of form no. 6.
8, form estalliana 'Garrett' Smith. Shell small, thin, whitish-corneous or yellowish, with the base and a 'band be- low the suture rose or dull purple, leaving the lighter tint in a broad zone or band. Occurs in Faahiti valley only (figs. 13, 14).
This form varies to yellow or corneous-yellow shells, with the spire corneous or more or less purple-tinted, lip whitish or with a purplish tint (figs. 15, 16).
Broderip's original description of P. rosea follows: "Shell ovate-pyramidal, roseate; whorls 6, longitudinally substriate, subdecussate with very close lines, the last larg- est; epidermis thin. Length %, diam. y$ inch.
"Var. a, purple-brown. Var. &, whitish, sutures and base of the last whorl roseate, epidermis yellow." (Brod.).

The shell is perforate, oblong-ovate, very thin, pellucid, slightly yellowish corneous, sometimes with a pale ruddy tint at the apex, the suture bordered with an opaque white line.

"It is more fragile and less slender than P. attenuata, the nearest allied form. The spire is less than half the length of the shell, and the suture is margined by a white line. The dull whitish peristome is widely expanded. The aperture is never dentate, and the yellow-corneous shell is faintly tinged with greenish.
"The animal varies from pale luteous-yellow to light brownish yellow. The soft parts, as seen through the trans- parent shell, are mottled with slate-colored spots. The foot is about the same length as the shell, and the ocular peduncles are very long and slender." (Garrett).

This species resembles the preceding [P. lineata], but it is distinguished 'by having the peristome less thick, by the umbilicus, of which the crevice is obliterated. Its altitude is 8 lines by 5 in diameter. Its spire is more swollen than in the preceding. The shell is thinner, and entirely corneous yellow. The Yellow Partula lives on the island of Borabora (Lesson) .

This is a rather solid, obesely ovate-conic shell, with straightly conic, acute spire and rather glossy surface. The spiral striation is generally weak in the median part of the last whorl, more distinct above and below. The first two whorls are flattened and slope steeply, giving the apex a more acutely conic shape than usual. Whorls 5, the post-embryonic ones rather convex, last whorl inflated. The aperture is somewhat oblique; outer lip reflexed and thickened within, white. Columellar margin only very little dilated at its in- sertion, near which it is thickened by a callous deposit on the inner margin of its face. The parietal wall is covered with a transparent callus, which near the lip-ends is thick- ened and white. There is no parietal tooth. The umbilicus is reduced to a very narrow, short chink. The color is variable :
1. Uniform pale yellow.
2. Pale yellow with brownish apex.
3. Isabelline, the first 2y2 whorls purple-brown or blackish violet.
4. Purple-brown, covered on the last whorl with a yellow cuticle, which is thin and transparent on the spire, the suture white (lilacina Pfr.).

According to Garrett, "notwithstanding its wide range over the island, it has not developed a single local variety. In fact it exhibits less variation than some of the species at the other islands which are restricted to single valleys."
Dr. Hartman and Andrew Garrett are agreed that Partula lilacina Pfr. is a color-phase of P. lutea. A figure of the type specimen in the British Museum is given, pi. 41, fig. 14.
6. Species of unknown habitats, probably from the Society Is.
The following will probably prove to be forms of some of the species already known from the Society Islands; but their status can only be determined by examination of the type specimens.
46. P. STOLIDA Pease.
"Shell elongate, ovate, dextral, rather dull, umbilicate, very finely roughened longitudinally and indistinctly under the lens striated transversely; whorls 5, convex; suture im- pressed; aperture elongately oval, rather small, not one- half the length of the shell, dentate, rarely edentate; lip somewhat roundly thickened, chestnut or olivaceous, ob- scurely and very finely striped longitudinally. Length 20, diam. 10^ mm. Tahitian archipelago. Terrestrial." (Pease).

Garrett, in his work of 1884, identified specimens of P. compressa as stolida ; but they cannot be made to agree with Pease's description. Pease himself, in 1871, gives the locality Raiatea; yet his testimony is of doubtful value. Perhaps
258 PARTULA, SOCIETY IS.
P. stolida will prove, if the type specimen can foe found, to be a form of the otaheitana series from Tahiti.
47. P. NITENS Pfeiffer.
Shell subperf orate, conic-ovate, swollen, rather thin; longi- tudinally very delicately striate ; glossy, diaphanous ; tawny- brown, above obsoletely, at the base broadly banded with buff. Spire conic, rather acute. Suture lightly impressed, whitish. Whorls 5, a trifle convex, the last about equal to the spire, rounded at the base. Aperture slightly oblique, acu- minate-oval; peristoine white, the right margin somewhat spreading above, moderately expanded ; columellar margin dilated, spreading somewhat over the perforation.

Partula simplaria MOREL., Journ. de Conchyl. 1853, p. 370, pi. 11, f. 13, 14.— PPR., Monogr. iv, 512.
This Partula is distinguished from P. varia by its swollen shape, obtuse summit, wider, less oblique and more rounded aperture, and finally the less thickened, less dilated peris- tome (Morelet).
This form has not 'been rediscovered, and its locality is uncertain. It stands near P. assimilis ; and by some authors has been considered a form of P. rosea or P. varia.
50. P. DIMINUTA C. B. Adams.
"Shell rather thick, ovate-conic; translucent, horn-colored, sometimes reddish, with a thin shining brownish horn-colored epidermis, which is much interrupted by transverse stripes ; with the tip white, with unequal, irregular, rather coarse transverse stride, and numerous excessively minute impressed spiral lines; apex subacute; spire rather short, with the out- lines slightly curvilinear; whorls five, a little convex, with a moderately impressed suture ; last whorl moderately oblique : aperture rather small, subovate, with a tubercle on the middle of the intruding part of the last whorl: lip much thickened, but narrow, with a regularly rounded surface: umbilicus small."

The figure does not agree well with Pease's measurements.
"We have no locality for the above species. It appears to approach the Marquesau type, and may be allied to lilacina Pfr. It is covered with a thin epidermis, which, when worn oft', would probably leave the shell without color, as is the case with ganymedes, Pfr. We have but a single specimen. ' ' (Pease.)
III. PARTUL^E OF THE AUSTRAL AND HERVEY GROUPS.
The few species of these groups are very closely related to those of the Society Islands, and no doubt are of common derivation.
In the Austral Group, Partula hyalina (see p. 180) is found on Tubuai and Rurutu (Oheteroa). No other Partula is known from the group. One island, Rurutu, has been somewhat carefully explored for land shells (see Garrett, Proc. A. N. S. Phila. 1879, pp. 17-30).
In the Hervey or Cook's Group, P. hyalina has been found on Mangaia and Rarotonga. P. assimilis Pse., a form very close to P. varia of Huaheine, occurs on Rarotonga. Pease
PARTULA, HERVEY IS. 261
has stated that the Baiatean P. liebe is found on Mangaia (Journ. de Conchyl. 1870, p. 401) but his records occasion- ally prove erroneous, and this one seems doubtful.
52. P. ASSIMILIS Pease. PI. 41, figs. 5, 9.
The shell is narrowly umbilicate, ovate-conic, rather thin; corneous or faintly yellowish-corneous, nearly uniform, but under a lens it appears to be very indistinctly marked with pale brown streaks; the early whorls are sometimes pale brown. 2% embryonic whorls with the usual subpunctate spiral lines, succeeding whorls finely weakly striate spirally, convex. The last whorl is quite convex, very indistinctly marked with more or less effaced spiral lines, or they may be almost wholly absent. Aperture slightly oblique, white or flesh-tinted within. Peristome white or flesh-colored, re- flexed and somewhat thickened within. Columellar lip di- lated above.
Length 18.3, diam. 10.5, aperture 10 mm. ; whorls 5.

Phila, ix, 1884, p. 80. — Partula cookiana 'Mouss.,' Schmeltz, Museum Godeffroy Catalog v, 1874, p. 92 (name only).
This species closely resembles the pale, yellowish form of P. varia of Huaheine, 'but differs by the thinner, less conic shell, with the spire more swollen, apex more obtuse and the lip is less thickened within.
Pease has described a "var. virgulata, shell generally shorter than the typical form, longitudinally streaked with light red; alt. 15, diam 9 mm. Barotonga."
Two specimens out of the Pease duplicates, from a series received from Dr. Hartman, have the summit purplish, like the form of P. varia figured on pi. 23, fig. 4, yet I do not feel certain that they are really from Barotonga.

IV. PARTITIVE OF THE SAMOAN ISLANDS.

This species differs from P. conica by its longer, more slen- der spire, absence of spiral striae except on the embryonic whorls and base, the darker tint, etc. It is said to be in- variably sinistral, and restricted to the island Upolu.
The color is greenish-yellow with more or less chestnut suf- fusion, sometimes darker in narrow streaks. The spire is darker, reddish brown; suture margined with a white line, narrower than in P. conica. The peristome is flesh-tinted, not so broad as that of P. conica, and the columella is gut- tered at its junction with the body. The umbilicus is ample, as in P. conica. Figs. 6 and 7 were drawn from one of the original lot collected by Schmeltz. Specimens measure as follows.
Length 28, diam. 17, aperture 16 mm. ; S1/-? whorls.
Length 27, diam. 16.5, aperture 16.3 mm. ; 5~y2 whorls.
Length 28.3, diam. 16.8, aperture 15 mm. ; 5% whorls.
Length 25.8, diam. 15.8, aperture 14.7 mm. ; 5y2 whorls.
A single specimen before me (pi. 32, fig. 8) has a much shorter spire than canal-is, not attenuated as that is. The color is dark chestnut, the spire dull dark purple. It is spirally striate below the periphery. Length 23, diam. 15, aperture 13.3 mm. ; whorls slightly over 5. Upolu. This may represent -a distinct subspecies.

The shell is sinistral, openly umbilieate, conic, with rather slender spire ; white under the thin yellow cuticle, the earlier whorls and a subsutural margin being white. The surface is glossy. Whorls 5%, the first half-whorl smooth, follow- ing 2~y2 whorls spirally engraved (fig. 8) ; on the following whorls the spire striae are almost wanting, but they reappear on the last whorl, which is very closely sculptured through- out with fine wavy spirals, stronger towards the base. The whorls are moderately convex, the last whorl rather swollen peripherally and very convex at the base. The aperture is ovate, rather oblique; peristome white, flatly, rather widely reflexed, dilated at the columellar insertion and somewhat excavated or grooved at its junction with the base. Parietal callus very thin, transparent.

In his descriptions of this species, Gould considered the large, more or less chestnut colored and smoother form later described as P. canalis to be a form of conica, and he also, by implication, included the dextral form, his words "in- terdum sinistrorsa" indicating that he had seen dextral ex- amples. It is obvious that Gould considered the sinistral form to be typical from his selection of sinistral examples for figuring, and from his comparison "resembling Bulimus Lcrvus in form"; yet his description is composite, the num- ber of whorls referring especially to the larger brown form (canalis) and the description of sculpture to the striate form here considered to be the true conica. Garrett's restriction of P. conica to the dextral form was not allowable under the existing conditions.
266 PARTULA, SAMOAN ISLANDS.
One of Gould's figures is copied, fig. 1. Other figures; drawn from the same type specimen are given (figs. 2, 3, no. 2687 A. N. S. P.). The whitish spiral lines on this shell are apparently pathologic.
This species is distinguished from P. canalis by the white spire of fewer whorls (5*4 to 51/^) , the more developed stria- tion of the last whorl and the comparatively larger aperture. In some examples, such as that shown in fig. 5, the spiral striation of the last whorl is hardly visible above the middle.
Gould's second locality for this species, "Raraka, " is a low island (atoll) of the Paumotu group, where it is prac- tically certain that no Partula lives.

Godeffroy & Sohn in Hamburg, p. 25, no. 1379 (March, 1865), is an un- described form, about which very little is known. Garrett placed upolensis in the synonymy of P. conica, but he seems to have had P. stevensoniana. A specimen purchased from the Godeffroys as P. upolensis (no. 59845 A. N. S. P.) as from Samoa, is nothing else than P. rosea cognata! This shell is figured, pi. 33, fig. 3.
55. P. STEVENSONIANA n. sp. PL 32, figs. 4, 9, 11 ; pi. 31, fig. 12.
The shell is openly umbilicate, ovate-conic, rather thin, whitish under a greenish-yellow cuticle, pale corneous or brown on the spire, suture edged with a white line. The embryonic whorls, except the first half-whorl, are deeply and very closely sculptured with engraved punctate spirals (pi. 31, fig. 12) ; following whorls and upper half of last whorl have rather widely spaced spiral lines, and the basal half of the last whorl is densely marked with wavy spirals. Spire short, conic, regular. Whorls 5*4, convex, the last equally convex except near the aperture where it is a little produced outwardly towards the base. Aperture ample, flesh colored within, but slightly oblique. Peristome reflexed, ivory white,, dilated and a little impressed at the columellar insertion.

This form seems to be known by the original lot only. It stands close to P. canalis and P. conica, having spiral sculp- ture like the latter, and coloration more like canalis. The cuticle is readily deciduous on the summit and in a band along the suture. The compact, subglobose shape distin- guishes it from allied species. It is shorter and wider than P. stevensoniana, and the aperture is larger.

This species is related to P. expansa, 'but differs 'by its narrower, less deeply penetrating umbilicus, longer spire, and especially by the spiral striation of the last whorl, which was described by Gould (see fig. 11, drawn from below the suture just back of the outer lip).
The opaque buff markings appear mostly as oblique streaks along the lines of growth, but they often tend to become trans- formed into spirally descending stripes, especially on the last half whorl, approaching the condition of the further evolved P. expansa. Often the cream tint predominates over the corneous or brown markings, which remain as streaks or spots.
PARTULA, SAMOAN ISLANDS. 269
Partula tryoni Hartman (pi. 31, fig. 5) is a zebrina in wliich the cream-white markings are reduced to mere flecks. While this color-pattern may possibly be characteristic of a local race, it is surely nothing but a form of P. zebrina. I have figured the type specimen (no. 4261 Carnegie Mus.). It was erroneously supposed to be from the Solomon Islands.
Partula actor Albers differs in no respect from zebrina. The type figure is copied, pi. 31, fig. 10.

This form differs from P. zebrina by its larger last whorl and shorter spire. Whether it is a true race or merely a phase of individual variation I have not the means of deciding. Fig. 9 is copied from that of Petit. Figs. 13, 16 represent specimens before me, measuring

In fig. 16 the white spots and stripes follow the direction of growth-lines, and stand on a corneous-brown ground.

About the middle of the penultimate whorl some white spots appear in the gray surface, the first ones being arranged along growth-lines; they rapidly change to spirally lengthened spots and belts which may be either continuous or interrupted on the last whorl. The last whorl is lightly marked with growth-lines but has no spiral stria:. It is in- flated and very convex at the base. Aperture lateral, dia- gonal.

It has been taken by Garrett and Schmeltz on Upolu. Pease's type specimen (drawn in my figure 14) is not fully mature, the expansion and thickening of the lip being incomplete. The pattern of opaque white stripes is interrupted, leaving

59. P. BRAZIERI Pease. PL 33, figs. 1, 2.
The shell is dextral oblong-acuminate, openly and deeply rimate, rather thin, glossy, whitish, having a very thin cuticle which on the last whorl is indistinctly streaked with very pale greenish-yellow, this color strongest in an indistinct belt below the periphery, and on the base. After the first half whorl the embryonic shell (fig. 2) is sculptured with close, punctate spiral striae; post-embryonic whorls sculptured with engraved spiral lines, which are rather widely spaced, and on the last half of the last whorl are obsolete above periphery. Spire conic, rather slender above. Embryonic shell of 2^ flat ivhorls; following whorls convex, the last whorl convex above, very full basally. Aperture slightly oblique, white within. Peristome narrowly reflexed, thickened within, white, tapering towards the upper termination, where it is continued in a small triangular callus filling the angle of the aperture. Columellar lip dilated inwards, a trifle grooved along its junction with the body; its outer edge continued a short distance upward on the parietal wall. Parietal callus transparent.

Pfeiffer 's description and figures (pi. 41, figs. 7, 8) are copied. The specimen drawn in figs. 6, 10, is slightly less swollen than Pfeiffer's, measuring, length 18, diam. 10.3, aperture 10 x 7 mm., whorls 5. The last whorl is whitish under a very thin pale greenish yellow cuticle. The spire is red-brown, darkest at the apex; on the penul- timate whorl it becomes paler in the middle, a darker shade continuing as a border above and below the suture as far as the lip. The growth-stria? are fine and distinct. Engraved spiral lines are fine and close, strongest on the last whorl. The whorls including the last are evenly convex; base con- vex, shortly rimate and deeply perforate. The lip is re- flexed, opaque white behind the reflection.

Shell perforate, ovate-conic, finely, widely decussate, stria- tulate, greenish. Spire couvexly-conic, regular, the summit rather obtuse ; suture not impressed, submarginate. Whorls 4:^/2, slightly convex, the last moderately convex, not as long as the spire, not ascending in front. Aperture rather small, subvertical (making an angle of 5 degrees with the axis), oblong, obliquely truncate above. Peristome expanded, angu- larly reflexed, whitish, somewhat labiate within, the margins not approaching; right margin curved in a long arch above; columellar margin vertical, wide, spreading, not folded with- in.

Partula subgonochila Mouss., Journ. de Conchyl. xix, 1871, p. 14, pi. 3, f. 4.
This species resembles P. varia to some extent, but the spire is less produced. Two lots from the Hartman collection are before me: No. 4284 Carnegie Mus. is from "Fortuna, Friendly Is.," coll. by Brazier (apparently Futuna, the type locality). The shell is thin, pale greenish yellow on the last whorl or two, fading to whitish above near the suture, the spire whitish. The spiral striae are rather close and very dis- tinct, and on the last whorl the peripheral angle is so in- distinctly indicated, that the contour remains rounded. The summit is quite obtuse. The lip is white. The largest of four measures, length 17, diam. 10, aperture 9 mm., whorls 4%. The smallest is 16 mm. long.
274 PARTULA, ROTUMA, FIJI.
No. 4285 Carnegie Mus., four specimens labelled "Tu- tuila. " Smaller than the preceding, the spiral striation not so strong on the last whorl, lip flesh-tinted. Length 141/^, diam. 9, aperture 8y± mm., whorls 4%
P. gonochila Pfr. is no doubt closely related to subgono- chila. In both the spiral striation of the embryonic whorls is very fine and distinct, and the pitting is conspicuous. P. gonochila is a more solid shell, darker colored, with the lip more thickened within, and the upper part of the spire more narrowly conic.
Rotuma species.
62. P. LEEFEI (E. A. Smith).
"Shell dextral, small, ovate, umbilicate, yellow-olivacous, pale below the suture and towards the 'apex; spire moder- ately produced, rounded at the apex. Whorls 5, a little con- vex, closely sculptured with delicate growth lines and very fine spiral striae, more or less obsolete on the last whorl; last whorl hardly descending in front. Aperture ovate, brown- ish inside, about half the total length; peristome white, ex- panded and reflexed, slightly thickened. Length 14, diam. 9 mm. ; aperture 6 x 31/2 mm. inside" (Smith) .

63. P. LIRATA Mousson. PI. 34, figs. 15, 16, 17, 18.
The shell is long ovate-conic, rather thin, rimate; white, pale yellowish, pale brown or rather dark liver brown with narrow paler streaks. Surface lusterless. The embryonic shell consists of nearly 3 whorls, the initial half whorl smooth, following half whorl very subtly punctate-striate spirally, spirals on the next whorl fewer, rather separated, and mainly on the upper part; third whorl with very weak spirals, which at the beginning of the post-embryonic shell become distinct but low cords. These increase in prominence to the last whorl, where there are 8-12 strong spiral cords above the periphery, with small, unequal cords in most of the intervals, and on the base are many smaller unequal cords and threads. These spiral cords extend to the lip-edge, which is creiiulated in all but old specimens. The last whorl is somewhat com- pressed laterally and convex at the base. Aperture ovate, oblique, colored within like the outside. Peristome narrowly expanded, thickened within ; columella dilated above. Parietal wall covered with a distinct but transparent callus, which bears a white callous tubercle far within near the root of the columella.

The single Fijian Partula has been found only on the small islands of the "eastern group," the genus being unknown on the large islands, where Placostylus 'abounds. The rarity of* Partula in this archipelago is at present inexplicable. The single species is one of the most distinct of the genus.
Mr. Layard stated in a letter to Dr. Hartman that he did not find the species on Taviuni or Lomma-lomma, in six weeks collecting on the former and a day or two at the latter place.

VI. NEW HEBRIDES AND SANTA CRUZ ISLANDS.
The Santa Cruz group, Banks and Torres Islands and New Hebrides form a group trending from N. W. to S. E. through about 10 degrees of latitude. The southern islands, Ero- manga, Aneiteum, are not remote from the Loyalty Islands which lie on a parallel fold, and have no Partulse. The northern or Santa Cruz end of the group approaches the Solomon Islands. The fauna is only imperfectly known, but seems to be somewhat related to that of the Solomon Islands, though much poorer and more primitive by lacking Papuina, Chloritis, etc. Many of the islands are high and wooded.

In the Monographia Pfeiffer mentions a var. 6, "a little more ventricose, rayed with isabelline 'and whitish."
Figs. 5, 6, -represents a specimen received from Cuming. This typical form of P. turneri has very pale narrow yellow- ish-green streaks on a white, faintly lemon tinted ground. There is a very inconspicuous band below the periphery. The base is markedly full, sack-like. The spiral lines are rather widely spaced and become very faint on the last half of the last whorl, except at the base. The figured example meas- ures, length 23.5, diam. 13.3, length of aperture 12.5, width 8.9 mm. ; whorls 5l/2. Another of the same lot is smaller, length 23, aperture 12 x 8.5 mm.
Var. perstrigata, nov. PI. 33, fig. 4.
The shell is pale buff or whitish, copiously marked with narrow chestnut or pale chestnut streaks; form, size and sculpture as in turneri.
One of the lots of this form, received from Dr. Hartman and said to have been collected by Geale, is marked "Tanna, New Hebrides," The type lot, no. 59848 A. N. S.

67. P. NEMATORAPHE Pilsbry, n. sp. PI. 35, figs. 1, 2, 3.
The shell is ovate-conic, rather thin, white under a thin, pale, yellowish green cuticle, which is darkest at the base, fad- ing upward to corneous-whitish on the upper whorls, the last whorl having narrow streaks of a darker shade at irregular intervals. Surface glossy. Embryonic shell of fully 2y2 whorls is very minutely punctate-striate spirally; following whorls are more convex, with rather distinct oblique growth- strias but only very faint and fine traces of spiral lines, ex- cept on the last whorl, which is distinctly striate spirally on the base and somewhat malleate behind the outer lip. The last whorl is full, rather swollen above the periphery, then tapers to the narrow, very convex base. The umbilical chink is deep and ample. Whorls nearly o1/^, separated by a well- impressed suture, which in the last two whorls is bordered above by a low cord defined by a groove. This margin is cov- ered by the ascent of the last whorl near the aperture, but may be traced faintly on the last whorl, though it is there very indistinct. The aperture is vertical, white within. Outer lip narrowly reflexed, white, thickened within. Colu- mellar margin broadly dilated above. The lip-callus extends somewhat more than half way up to the insertion, where it terminates in a small but distinct nodule. Parietal callus thin, transparent.

This species was thought by Dr. Hartman to be P. alabas- trina, but Pfeiffer's description of that shell does not apply well to these specimens in several respects. Fig. 3 represents the suture just behind the aperture, showing the end of the suprasutural cord.
68. P. EXIMIA Hartman. PI. 33, fig. 11.
The shell is very deeply rimate-perforate, pyramidal. The unique type is a "dead" shell, denuded of cuticle, grayish white, but the color is preserved on the parietal wall, indicat- ing a very pale buff ground marked with narrow brownish- yellow streaks; the coloration perhaps intermediate between that of typical P. turneri and P. caledonica. The apical whorls resemble those of P. brazieri, though the second may be slightly more convex. Subsequent whorls are quite convex, and traces of fine, rather spaced spiral striation, just as in P. caledonica, may be seen on the penultimate and next earlier whorls, the last whorl being 'without spirals except around the umbilicus. Oblique growth-wrinkles are rather distinct. The last whorl is compressed laterally and very convex at the base. Aperture only half the total length, slightly oblique; peristome white, expanded, well thickened within; having the usual deeply placed fold at the root of the colu- mella. Length 23, diam. 11.7, length of aperture 11.5 mm., width 7.8 mm. ; whorls 5%.

This species stands very close to P. caledonica, from which it differs by the slightly more lengthened spire, and perhaps the paler, less brown color. Hartman, in 1896, wrote me that he considered eximia a synonym of macgillvrayi, having

Spire slender, long. Embryonic whorls conic and but slightly convex, much as in P. brazieri. Subsequent whorls convex, the penultimate and last whorls very strongly convex. The later part of the last whorl is flattened laterally ; base very full, sack-like. Spiral lines well spaced on the penultimate whorl, wanting on the last except at the base.

In coloring, this species is like P. turneri except that it has no band below the periphery ; but it is a much more slender shell with a deeper suture. It stands very close to P. eximia, but differs by the more swollen last whorl and consequently wider aperture, and by the greener color. Described and figured from two cotypes in Hartman collection, no. 4305 Carnegie Museum.

Dr. Hartman 's description and a copy of his figure (fig. 9) are given. The specimens before me from Sitova Island (fig. 10) are smaller, with a narrower lip than the Aura Island type. The apex is like that of P. brazieri; later whorls are

engraved with distinct spiral lines which are somewhat separ- ated on the penultimate whorl and front of the last one, 'but on the latter half of the last whorl the spiral striae are close, with deeper lines at short intervals. The later whorls are strongly convex, but the last becomes compressed laterally, towards the aperture, and is sack-like below. The umbilical chink is deep and wide. The color is a slightly bluish milky white, without markings. Length 21.8, diam. 12.2, length of aperture 11.2 mm. ; whorls 5%.
"While it is closely related to P. caledonica, macgillivrayi, eximia etc., this species is distinct by the absence of color streaks and the persistence of spiral striae over the whole last whorl.
I have been unable to find an Aura Island in the New Hebrides. Probably Arag is intended. Sitova is also un- known to me.

The shell is deeply rirnate, rather thin but solid, ovate- conic. The last two whorls are whitish (probably denuded of cuticle) below the suture, elsewhere covered with a thin greenish yellow cuticle with some inconspicuous darker streaks. The spire lacks cuticle and is very pale brownish, almost white. Apex obtuse; embryonic whorls slightly convex, punc'tate-striate, not so high as in P. fraterna. Subsequent whorls more convex, sculptured with distinct, regular en- graved spirals, which are somewhat weaker and more widely spaced on the upper part of the last whorl, closer and deeper on the base. Last whorl is strongly convex, its last half however being perceptibly compressed laterally; base very convex. The aperture is but slightly oblique, symmetrically ovate, faintly flesh-tinted within.

This is said to be a common species. It differs from P. fraterna chiefly by the better developed spiral striation, lower embryonic whorls and shorter spire ; yet it is not improbable that intermediaite forms occur.
An embryo of 2i/> whorls, 4.9 mm. long, is figured, pi. 34, fig. 8. The first half whorl is pale brown and smooth, fol- lowing whorls are densely punctate-s'triate above. The peri-

pliery of the last whorl is angular, base with no spiral striae. The columella is long, vertical, rather heavily calloused, taper- ing and somewhat excised 'below, not unlike the columella in some forms of Obeliscus. The axis is perforated.
Mr. Sykes states that the specimens from Lo Island col- lected 'by Mr. J. J. Walker are a local race.

The shell is rather widely and deeply rimate, solid, ovate- conic. Last whorl whitish below the suture, elsewhere cov- ered with a faintly green tinted yellow cuticle which is in- distinctly streaked with 'brighter yellow ; the spire brown, be- coming darker towards the apex; suture well impressed, marked with a whitish line. Apex obtuse, the top more rounded and the sides less straightened than in P. caledonica, brazicri etc. ; embryonic whorls punctate-striate, convex ; sub- sequent whorls convex, engraved with rather delicate spirals, almost obsolete on the upper part of the last whorl, but dis- tinct though delicate on the base. The last whorl is a little flattened laterally behind the aperture, convex and somewhat sack-like basally. Aperture fleshy within, ovate, hardly oblique. Peristome rather narrowly expanded and reflexed, thickened within, tapering at the upper end. Columellar margin broadly reflexed, dilated and biramose above. Parietal callus thin, transparent, thickened at its junctions with the lip ends.

This rather stout, opaque species has some resemblance to P. carnicolor, but differs by its shorter form, wider umbilical fissure and the much more convex base. The embryonic whorls are more convex than in the group of P. turneri, and the apex is more obtuse. It is closely related to P. auraniana

but differs by the longer spire of decidedly over five whorls, while auraniana has barely five or fewer. The spiral striation is not nearly so well developed in fraterna, and the second whorl is higher.
A second example in the type lot is 19 mm. long, but not quite fully mature. Description and figure are from the type, no. 4294 Carnegie Museum.
75. P. CARNICOLOR Hartman. PI. 34, figs. 1, 2, 3.
The shell is oblong-conic, moderately solid, rather narrowly umbilicate ; fleshy-brown under a very thin yellowish-corneous cuticle with narrow darker greenish-yellow streaks (the cuticle mostly wanting in the two adult cotypes, which were "dead" shells). Spire straightly conic. Embryonic shell rather large, conic, densely punctate-striate spirally, bicolored, the lower part of each whorl brown, darker than the upper. Subsequent whorls convex, marked with growth^lines but without spirals except at the base, which is very closely marked with wavy spiral stria?. Last whorl is evenly convex throughout, tapering basally. Aperture ovate, oblique, flesh- tinted inside. Peristome narrowly expanded and reflexed, white on both face and reverse, well thickened within; colu- mellar margin dilated above, distinctly grooved at its junction with the whorl.

' ' The above is of the type of P. repanda Pf r. inhabiting the same group of islands. It is smaller than that species, more abbreviate in shape, thinner, distinctly striate, columella no- dose, and of a different color." (Pse.}.
The figures are from a specimen in the Hartman collection (no. 4244 Carnegie Mus.). It measures 13 mm. long, 8 wide, aperture 7.3 mm. long, and has 4^ whorls. It is bluish white, the spire pale brown. The columellar nodule, mentioned by- Pease, may be seen in fig. 9, under a lens. While smaller than Pease 's type, I think the specimen is probably identified cor- rectly.
I suspect that P. concinna was based on a stray example of P. taniata nucleola. The description certainly favors that theory, and the Hartman example figured seems hardly separ- able from that Moorean shell.

The shell is long ovate, moderately strong, white under a thin cuticle which is gray on the spire and base, yellowish- brown in the middle part of the last whorl, where there are very faint traces of spiral lighter and danker bands. The spire is rather long, whorls convex; suture well impressed. Just above the suture may be seen an inconspicuous ridge or angle —the periphery of the penultimate whorl. The embryonic sculpture is worn; subsequent whorls have very even and regular spiral striation, which may be slightly weaker on the upper part of the last whorl. Last whorl is convex at first, on the last half becoming flattened laterally; very convex, sack-like, at the base. The umbilical fissure is short but deep. Aperture slightly oblique, ovate, small, white inside. Peris- tome well expanded, thickened within, white, columellar mar- gin dilated above, and slightly grooved where it joins the preceding whorl. Parietal callus transparent.

In shape and sculpture this species resembles Partula re- yiilaris, but it differs by the very distinctly marginated suture, the less approaching terminations of the lip, the better de- veloped callus within the lip, and the coloration, which seems to be quite characteristic. It will probably be found to be a species of the Solomon Island or the New Hebrides.
This species was in the Hartman collection under the name "P. laevigata Pfr.," but on the label Dr. Hartman expressed the opinion that it was not that species. It has little in com- mon with Icuvigata, which evidently belongs to a wholly dif- ferent group. Named in honor of Dr. J. W. Holland, Director of the Carnegie Museum.

Pfeiffer's figures of the type are copied, pi. 36, figs. 10, 11.
Specimens from Shortland I. are figured, pi. 36, figs. 13, 14, for comparison with P. similaris and other related forms. The spire is shorter than that of P. similaris, with not quite 5 whorls, the last one convex, shaped about as in similaris, being much less compressed laterally than P. coxi. The lip is only very slightly thickened within, — much less than in coxi, similaris etc. The spiral striation is weaker on the last whorl than in the allied species. Color very pale honey yellow, slightly transparent. The suture is marked with a whitish line. Sometimes a margining thread may be seen above it on the last whorl, but in other shells this is con- cealed. The last half whorl is impressed just below the suture, forming a sort of margination there.

This unfigured species is probably a form of, or very closely related to P. micans, which has a slightly larger aperture, but no other difference so far as the description shows.
90. P. coxi 'Angas' Hartman. PI. 36, figs. 1, 2, 3, 4.
The shell is oblong-conic, openly rimate and perforate, thin, pale yellowish-corneous throughout, imperfectly transparent, not glossy.- Spire conic, the apex slightly obtuse; whorls 4V2 to 4%, all convex ; 2% embryonic whorls sculptured with punctured engraved spirals, following whorls marked with growth-lines and fine engraved spirals, which continue strongly and evenly developed on the last whorl, which is especially convex above the periphery and at the base, and somewhat tapering between. The aperture varies from moderately to very slightly oblique, ovate ; outer and basal lip narrowly re- flexed, slightly thickened within except at the posterior curve of the outer lip where it is thin; on the columellar side the thickening extends about half way up to the insertion. The columellar lip is dilated and two-branched above.

This shell stands near P. pellucida Hartm. but differs by its longer, less obtuse spire.
Dip to the beginning of the last whorl the shell is biconic, acutely angular or earinate at the periphery, the angle bear- ing a projecting cord wider than the other intervals of the spiral sculpture. The axis is perforate at all stages of growth.
P. micans has the last whorl less compressed laterally, and the lip is much less thickened within.

One adult and two young examples in the Hartman collec- tion, no. 4246 Carnegie Museum, are stated on the label to have been compared with "Brazier's type example." They are labelled "Ysabel, Solomon Is. (coll. Cox)." The adult shell is figured (fig. 6). It is white under a very thin, clear corneous cuticle which is partly worn off in ragged streaks. The surface is rather coarsely sculptured with close wavy

Whorls 4*4, convex, the latter part of the last whorl somewhat flattened laterally and slightly concave just below the suture, w*hich is whitish. Aperture slightly oblique, oval; peristome continuous, the outer lip slightly expanded, thickened within except near the posterior angle ; parietal callus heavy for so small a shell, its edge distinctly raised. Umbilical chink short but deep. Length 11, diam. 6.9, aperture including peristome 6x4 mm.
Another specimen (pi. 36, fig. 5) from Dr. Cox, (no. 59873 A. N. S. P.), measures, length 11, diam. 6.7, aperture 6.5 mm. long. It is similar but has the corneous cuticle entire and the parietal callus weak in the middle. There is a narrow slightly prominent though hardly raised girdle at the peri- phery, where the cuticle is more persistent, and this is visible above the suture for a short distance behind the aperture. This structure is so weak that it might readily be overlooked, but it is visible in both of the examples seen. The aperture is decidedly oblique in this shell.
This species has a shorter spire than the preceding forms and is a little smaller, otherwise they seem to be closely related.

A slender, acute pale species, of which I give the original description and figures (pi. 36, figs. 17, 18). These, if ac- curately drawn, indicate a shell with longer spire than any I have seen. Port Carteret examples before me received from Cuming (pi. 36, figs. 15, 16) are nearly white with the spire pale flesh-colored. The surface is glossy, with sculpture of growth-wrinkles and extremely fine and close engraved spirals. Above the periphery of the last whorl these spiral lines be- come faint, more or less obsolete. The apex is rather pointed. The last half of the last whorl is compressed laterally, the base saccate. The aperture is vertical, ovate ; the lip narrowly reflexed and thickened within, thin near the posterior angle, the outer margin slightly sinuous. The umbilical chink is rather small.
Length 17^, diam. 8y2, aperture 9x6 mm. ; whorls 5.
Length 16, diam. 8%, aperture 8% x 6 mm. ; whorls 41/£.
It differs from P. coxi, kubaryi etc. by the more delicate, more minute and crowded spiral lines of the penultimate whorl and base.

"P. elongata Pease, and P. gracilis of the same author, from the Tahiti group, closely resemble this species. The former is rather larger and broader, not so strongly spirally striated, and more or less striped with pale brown. The latter has a longer aperture, rather more convex apical whorls, and a pecu- liar bulging at the lower part of the body-whorl. P. minuta, Pfr., also from the Admiralty Islands, is similarly sculptured, but of a totally distinct form." (E. A. Smith}.
Mr. Smith's description and figure (fig. 7) are copied. One of the specimens from Wild Island before me is smaller, length 141/2, diam. 7, aperture 7.2 mm., with 5 whorls. The aperture of this example is quite oblique (pi. 37, fig. 6). In a larger specimen the aperture is almost vertical. The peri- pheral cord common to other species of the group is visible above the suture, which is also very distinctly marginate be- low, on the last half whorl. Spiral striation is very dis- tinctly developed throughout.

specific distinction between P. similaris and P. woodlarkiana. The type specimens of both were returned to Australia by Dr. Hartman. I have copied a photograph of the type of P. similaris in fig. 13. Specimens from the Trobriand Is. are also figured, pi. 37, figs. 14, 15.' The shell is somewhat transparent grayish yellow, flesh-tinted near the apex. The surface is very distinctly and beautifully decussate, the deeply engraved spiral lines being made wavy by the fine, rather distinct growth-striae. The last whorl is convex, narrowly umbilicate, and sometimes margined below the suture on its last half. A narrow margining thread may be seen in places above the suture. The suture itself is edged throughout with a fine white line. The callous thickening within the lip thins out rather gradually above, not abruptly as in many related species, but it stops abruptly about half way up the colu- mellar margin. At the columellar insertion there is a slight
groove.

This species is more lengthened and thinner than any other known to me. The penultimate whorl is longer than in the species already mentioned [P. otaheitana, rufd, lineata, lutea] . The last whorl, finally, is but little dilated, little swollen. The aperture is directed to the right. It is higher than wide, with the peristome thick, a little dilated in front of the um- bilical chink. The surface of the shell is very finely striate longitudinally and transversely, hence covered with a fine and granulose network. The aperture is white. All the rest is uniform light gray.

This Partula is the largest species known to us. It is 10 lines long and 7 in diameter. The shell is thick, solid, with the mouth on the right side, large and oval, provided with a thick flange, the umbilicus very open back of the columellar plate adnate to the peristome. The spire is short, conic, ob- tuse at the apex, the whorls parted by a quite deep suture. Last whorl large, ventricose, very finely striate lengthwise. The shell is whitish, but covered with a bright fawn epidermis. The peristome is simple in the young. (Lesson} .

An unfigured species, not recognized since its description. So far 'as I know the Coquille landed only at Port Dorey (near Mt. Arfak and the N.-W. cape of Geelvink Bay), and probably this shell came from there. The visit was in July- August, 1824. Hartman, at one time, identified P. canalis as P. ~bulimoides. From Lesson's description, the shell must be very different from other species of the southwestern Pacific.

XI. PELEW ISLAND SPECIES. Section PALAOPARTULA n. sect.
Straightly conic forms with high embryonic whorls and very deeply engraved later whorls, the last compressed later- ally and' sack-like below, with a very ample timbilical area and deep perforation. The aperture is unusually long, and the peristome is thin and very broadly reflexed. Type P. thetis.
The three closely related forms from Pelelu (Pililu) stand apart from all other Partulas. They have some appearance of being a branch from the Melanesian group. The coloring, the slight differention of a peripheral belt (marked with finer spiral strias), and the high apical whorls, recall species of the New Hebrides and Solomon Islands.

This third species, according to Semper, is not quite so thin as the other two. The aperture is a little rounder, and the summit is mamillate, a feature totally wanting in the two other species.
A specimen before me, figs. 5, 6, no. 4272 Carnegie Mus., is distinctly streaked with greenish-corneous and whitish on the last whorl, growing ruddy on the spire. The apical whorls are very high, much as in P. brazieri (pi. 33, fig. 2) . The rest of the whorls are very distinctly and beautifully sculptured with close, deeply engraved spiral lines. The lip is thin throughout, not perceptibly thickened within, and tapers rapidly from the upper third to the insertion. The columella is straight and vertical.

A large, bulimoid species having much the appearance of a small Borus. Pfeiffer's type, figured in Philippi 's Abbil- dungen (copied in my fig. 9), is the rather obese form further illustrated by figs. 7 and 8. The embryonic shell is very densely striate spirally but is usually worn in adult shells. The rest of the whorls have distinct spiral striae, which in the typical form are deeply engraved throughout, but on some examples they 'become rather weak on the last whorl. The ample aperture is dull purplish inside in some examples, white in others. The white lip is reflexed, and a little thickened within. The chestnut color of the shell is sometimes varied by a faintly darker line at the periphery. Examples measure :
Length 27, diam. 18.3, aperture 16 x 11.8 mm. ; whorls 5l/3.
Length 27, diam. 17, aperture 15.5 x 11 mm. ; whorls 5y2.
Length 28, diam. 17, aperture 15 x 12 mm. ; whorls 5y2.
The form called brumalis by Reeve (pi. 38, fig. 10, copied
310 PARTULA, CAROLINE ISLANDS.
from Reeve) is somewhat more elongated, yet it intergrades fully with guamensis, judging from examples 'before me (see measurements above). The forms figured by von Martens from the ruins of Nanmatal belong to this more lengthened type. They further illustrate the variation in shape of aper- ture caused by the different degrees of inclination of the columella, and hence have been copied in my figs. 11, 12, 13, 14 of pi. 38.
Dr. von Martens gives the size as length 26, diam. 16, aperture 15 x 11 mm.
Both Hartman and von Moellendorff have renamed this species, objecting to the name guamensis "inasmuch as this mollusk certainly does not live on the island of Guam, where my friend Quadras collected for more than two months with- out finding it" (Mlldff.} ; but if the name be rejected on that ground, the species should be called brumalis Rve.
P. GUAMENSIS GRANDIS Moellendorff is "much larger, diam. 19, alt. 30.5 mm., less solid, spiral sculpture somewhat less marked, peristome more expanded, less labiate; 5% to nearly 6 whorls. Ponape, coast region (Etscheid, Kubary).
"#There are three color- variations, viz., dark purple-brown with violet lip (typical) ; castanea, pale -chestnut colored with white lip ; and flavescens, pale greenish yellow. The last named albino is rather rare " (Mlldff.}.
106. P. MARTENSIANA Pilsbry, n. sp. PI. 38, figs. 15, 16.
The shell is ovate-conic, solid and strong, opaque, with a small, compressed umbilicus; beneath a yellow cuticle (which is partially lost from the type specimen, a "dead" shell), the substance of the shell is dull flesh color, becoming darker on the spire, the first three whorls being dull brownish purple. The spire is conic, summit slightly obtuse; the early whorls are worn and show no sculpture ; last whorl has no spiral in- cised lines, but some traces of fine .spiral wrinkling may be seen in places, though it is very fine and weak. Whorls 5, convex, the last convex throughout. Aperture is very slightly oblique, flesh-pink within; peristome white, very slightly ex-

Related to P. guamensis, from which it differs by the ab- sence of distinct spiral lines on the last whorl, the less ex- panded but more thickened lip and more contracted aperture. It was identified by Dr. Hartman with P. rufa Lesson, but that is a smaller, especially narrower shell.
The type specimen was collected by John Brazier "on the banks of the Leila river, Chabroul Harbor, Ouhalan or Strong's Island," according to a letter from Brazier to Dr. Hartman, written at Sydney, June 18, 1885.
A second specimen in the Hartman collection measures, length 21.5, diam. 14. aperture 11.7 mm. It is an old shell, faded and broken.
107. P. RUFA Lesson.
This species resembles especially the preceding [P. ota- heitana] , but the aperture is turned to the right. The spire is less lengthened, more swollen, more conic. The last whorl is proportionally larger. The aperture is more oval and less contracted, and its peristome is not so thick. The color is dirty red. Length 8, diam. 4 lines (Lesson).

Lesson's brief description indicates a shell resembling P. guamensis in general features, but much smaller than any other known species of the group, — about 16 or 17 mm. long, 8 or 9 wide. It is hardly possible that the identifications of P. rufa made by either Hartman or von Martens are correct. This was also the opinion of Dr. 0. von Moellendorff. P. rufa still awaits rediscovery.

The shell of this species is oval, long, with conic spire, a half whorl swollen. The aperture opens on the right side. It is contracted by a thick rim recurved 'backward, and di- lated at its junction with the columellar axis, a little in ad- vance of the umbilical crevice. It. is nearly of the same size and shape as the 0-Taite Partula [P. otaheitana], -but it is constantly a little shorter and more inflated. The color is pale yellow with two ribbon-like stripes of fawn, one short, surrounding the opening of the umbilicus, the other running around the middle of the large (last) whorl, and covered by the suture on the spire. Length 8, diam. 5 lines (about 16x10 mm.). (Lesson).

This species was 'considered the same as P. suturalis Pfr., of Moorea, Society Islands, by Mr. Garrett in his paper of 1884, but later he doubted the identification, in a letter written to Dr. Hartman. Mr. Brazier, who visited Ualan, did not find Lesson's species (H. H. Smith, Ann. Carnegie Museum i, p. 446).
The general appearance of the shell is that of a Society Island species; but the Coquille did not visit the island of Moorea where the forms (P. suturalis, P. t&niata) best agreeing with Lesson's description occur, but only Tahiti and Borabora, ob- taining P. otaheitana at the former, P. lutea at the latter place. They were at Ualan in the Carolines on June 15th, 1824, anchoring in Coquille Harbor on the N.-W. side of the island.
In view of the general reliability of the locality records in the Zoology of the Coquille, and the imperfection of our knowledge of the shells of Ualan, I think it not improbable that P. lineata may eventually be found there.
PARTULA, MARIANNE ISLANDS. 313
The nodule on the parietal wall, shown in Lesson's figure tout not mentioned in the description, is a feature appearing also in species of the Society, Fiji and Marianne groups. The relationships of the species are obscure. I would not venture to assign it to any of the subgenera.

Ferussac 's type of P. gibba was a small, short example. His figure is copied (pi. 39, fig. 1). The last whorl is pale yellowish-corneous, spire of a rather peculiar dull scarlet

color. The last three whorls have an opaque white 'border be- low the suture. The last whorl varies in the degree of swell- ing, and in small individuals is usually angular in front, at the periphery; base very full and convex. Umbilicus small and deep, more rounded than usual in Partula. The engraved spiral lines are distinct and not very close above the periphery, more crowded on the base. The aperture is oblique, white in- side in the pale, variously colored in the dark varieties. The peristome is white, or in some forms flesh-tinted. The outer lip is expanded, rather heavily thickened within, the callus somewhat abruptly terminating at the beginning of the curve to the upper insertion; columellar lip dilated. Figs. 2, 3, 5 and 6 represent individuals of the typical P. gib'ba. Be- sides the typical coloration (a) described above, there are shells with (6) reddish spire and brown last whorl (fig. 2), and others (c) of the typical pale tint and a white spire (fig. 9). These forms occur together in some lots before me. Other forms are :
(d) Corneous-white, somewhat transparent, very thin (pi. 39, fig. 11).
(e) Drab with the spire dull dark purple, lip fleshy (fig. 7). (/') Lilac, the spire darker, aperture brown within (fig. 8). (g) Light reddish-brown (fig. 5).
(/O First 21/) whorls foi colored, brown and whitish, the rest corneous-yellow, becoming dull purple near the lip. Interior lilac, with a brown streak within the lip, which is flesh-colored (fig. 10).
There is considerable variation in the solidity of the shell, and the thickness of the lip-callus. The latter is sometimes perceptibly nodulous, as in fig. 6.
To what extent the variations in color and texture are local or racial is unknown. All have a white sutural border. Ex- amples measure as follows:
(a) Length 17, diam. 11.3, aperture 9.8 mm. long.

(/i) Length IS1/^, diam. 13, aperture 11 mm. long.
Specimens of a lot consisting of rather solid shells of forms b and g show a thin callus or low tubercle on the parietal wall, approaching P. bicolor in this respect (figs. 5, 6).
P. mastersi Pfr. seems to be identical with gibba, judging from the description and specimens before me. It is de- scribed as rather solid, buff, fleshy or violaceous, sometimes banded with brown on the upper whorls. It is 17 mm. long, with the aperture 10% mm.

Peristome brownish outside and within. Whorls 4, convex, the last half the length of the shell. Peristome thickened, narrowly and equally expanded.

The above may be distinguished from P. gibba, which occurs at the same locality, in being of smaller size, last whorl not inflated, and in its color (Pse.).
This form intergrades with P. gibba, and should evidently be regarded as a subspecies of that, chiefly distinguished by having the last whorl less swollen than in typical gibba, and by having a callous nodule deep within, on the parietal wall near the columella. This nodule is seen very weakly de- veloped in some examples of gibba. Other supposed differ- ences are even less constant.
Pease's original description reproduced above is not good; his figure is copied, pi. 39, fig. 17. The shell is rather solid, with sculpture of spiral lines as in P. gibba. On the last whorl these lines are very fine and close on the base, but a

little more separated above the periphery. The surface is glossy. The lip may be narrow and nearly uniform in width, but usually it is rather strongly thickened inside, the callus abruptly discontinued near the posterior curve. The color -of the lip is quite variable. There is a callous nodule deep within, near the columella, but it is very variable in size. The suture may be marked with a whitish line, but often this is absent. No specimen I have seen has a well developed white band along the suture, such as is usual in P. gibba The color-patterns known are as follows :
(a) Straw colored or isabelline, with a reddish-brown band above the suture almost to its end, and covering the first li/o whorls; outer half of the lip brown, inner rim white. This is the typical coloration (figs. 12). (&) First 2 whorls purplish-brown, the third pale below the suture with the dark color fading (or the subsutural pale area may extend nearly to the apex) ; last 2 whorls straw yellow or pale isabelline with faint or distinct brownish streaks ; back of lip reddish or yellow ; lip narrow, very pale brown; surface rather dull (fig. 18).
(c) Same as the last but without brown on the spire; sur- face lusterless (fig. 15, 16).
{d) Pale uniform sulphur-yellow throughout, the lip
brown- tinted or brown-edged (fig. 14). (e) Pale sulphur-yellow, the lip heavily thickened and
pure white (fig. 13). The size varies as follows :
(a) Length 17, diam. 11.5, aperture 10 mm.; whorls 4%. {&) Length 17, diam. 11, aperture 9.5 mm.; whorls 4i/o.

This form was at first supposed to be from New Ireland, but was soon shown to come from Guam. It is a narrowly iimbilicate, thin shell, copiously striped with corneous and opaque white, with more or less suffusion of pale lemon yel- low. In the more fully colored examples there are also many olive-yellow lines among the stripes, scarcely visible except under a lens. These lines dilate at the periphery, which therefore, appears to have a faint band. This pattern is shown in fig. 4. Other examples lack the dark lines and peripheral band. The embryonic shell is very densely and distinctly engraved spirally, the lines disappearing towards the apex ; the first whorl is weakly plicate radially. The last whorl is marked with rather widely spaced spiral lines, closer on the base. In the typical form these lines are rather weak. The last whorl is very full at the base. The lip is white, narrowly reflexed, very little thickened within. Specimens measure :
Length 19, diam. 11.2, aperture 11 x 7.1 mm. ; whorls
Length 17.5, diam. 11, aperture 10 x 7 mm. ; whorls
Length 17, diam. 10, aperture 9.5 x 7 mm. ; whorls 4%.

A form (pi. 41, fig. 2) collected by Quadras is smaller, with a brown band above the suture on the first 2y2 or 3 whorls of some specimens, the spire in others being -pale lemon tinted. The last whorl has the typical coloration. The aperture is more or less brown inside in those with a dark summit. The first whorl does not seem to be plicate.

Bulimus macleayi Brazier from Yule Island, other islands in Torres Strait, and Queensland, was described as a Papuina in this Manual, Vol. XIII, p. 121. It has been referred by Hedley to Partula (Proc. Linn. Soc. N. S. Wales ix, 1894, p. 387, pi. 26, f. 22, 23) ; the radula figured by him has marginal teeth resembling those of Partula, yet differing by the larger size of the second cusp, whereas in Partula the inner cusp is the larger. The central tooth has no side-cusps. There are 160 rows of 40,6,1,6,40 teeth. If the pallial organs etc., confirm the relationship claimed by Hedley (but which I doubt) this species will form a new genus of Partulidce, char- acterized by the unexpanded, thin and simple lip of the shell, and the absence of the typical apical sculpture of Partula.

Shell moderately thin, polished, dark yellowish-horn color, obtusely lanceolate. Whorls 71/4, marked with very faint lines of growth only; sutures impressed. Columella descend- ing in a very oblique curve; peristome simple, bent slightly inwards above. Aperture inversely, elongately auriform. Alt. 21.75, diam. 9, alt. of aperture 7.75, diam. 4 mm. (Preston}.
Ceylon.
Glessida sinhila Preston, Records of the Indian Museum iii, pt. 2, no. 6, p. 135, pi. 22, f. 14 (June, 1909).
"Allied to G. inornata Pfr., but easily distinguished from that species by its much more slender form. ' '
P. 173. Add fig. 13 to those cited after P. BELLULA.
P. 287. The name Partula minor Hartman might by some be considered unavailable on account of the earlier B. roseus var. &. minor, of Pfeiffer; yet it appears that Pfeiffer here intended the word minor as a description, not as a name.
P. 313. Under XIII etc., read Section MARIANELLA, in place of "MARIANNA. " The former term was used on p. 166.
